3 Ham Antennas You Can Homebrew For This Spring

Yagi Ham Antenna
 There are 3 Ham Antennas you can homebrew for your Ham Shack this coming spring. The three I like are the yagi, moxon and quad antennas. When your thinking of a yagi ham antenna you have some different ways of building one. The first is made with pvc conduit pipe and wire. The only issues are that depending on the ham band it may be somewhat heavy and it may not hold up for too long in the weather. The other choice is to use some aluminum tubing. The pvc may be cheaper to use and is good for experimenting with. The aluminum tubing can be bought through hygain and DX Engineering just to name a few.
 The second ham antenna is the Moxon Antenna. Basically it is a rectangle with two pieces of wire. There are many different websites and videos on the internet that can be a tremendous help in designing and building a moxon antenna. If it's for six meters or 10 meters it can be made out of pvc conduit pipe. Once again it may be a little heavy and bend or droop. I would suggest putting some dowel rod or smaller metal conduit inside the pvc pipe for extra added support. Check out the Moxon Antenna Project for some awesome information. If you are looking for more Beam Antennas Click This Link For Beam Antennas.
 My third choice for a good ham antenna is the quad antenna. These antennas in the 2 meter, 6 meter and 10 meter bands can be made and are not too heavy. Another idea for the spreaders is to use 16 foot telescoping crappie fishing poles. These can actually be used for all three types of antennas. The nice part about them is that they are made of fiberglass and will hold up in the weather. The other added plus is that they are not too expensive. Cabelas on the internet has them for a good price.

The 3 Ham Radio Licenses You Will Need To Transmit

 You can buy a Ham Radio and listen without a ham radio license. If however you want to transmit on a given band or frequency you will need the proper ham radio license. There are many websites on the internet where you can download study material or download a program to study from. I myself had some older books and also used the material off the internet to do my studying. My honest advise is to purchase the books and the cd program for your computer. If you can go to one of the ham radio classes in your area I would advise that also.
 There are 3 Ham Radio Licenses that you will need to transmit on various bands. I will list them below.
  1. The Technician 
  2. The General
  3. The Extra
 You may find that most Hams only go up to the General License as it provides the opportunity to transmit on most of the high frequency bands such as the 20 meter, 40 meter, 80 meter and 160 meter bands. There are portions that you can not transmit on only if you have the Extra Ham License. I myself have the Technician and the General Licenses. I am thinking about spending the time and going for the Extra Ham Radio License.
 Never try to transmit on any Ham Radio Band without a the proper license. If you do and get caught you could face a nasty fine from the FCC. Si it is best to get the license and enjoy the Ham Radio Hobby. You will be amazed at what a simple basic ham radio and a wire dipole antenna can do. Below are some places at Amazon where you can purchase the proper study material.

Simple Ways To Build Ham Antennas

 The best way to research what antenna to build is first determine your safe area to mount your antenna. Stay far away from power lines. Next determine what frequency you will be transmitting on. That will determine the size of the antenna. In other words a 2 meter antenna will be much smaller than a 20 meter antenna. The next thing is what are you going to build your antenna out of. Many Hams use pvc pipe. You would be surprised as to the designs you can come up with using electrical pvc pipe and various connectors.
 Pvc pipe is not all that expensive and antenna wire is not too expensive. It's all up to your imagination. Think about a certain antenna such as a quad antenna and the research it on the internet. Download some of the antenna building programs that are free. Then look for an antenna calculator and start your project today. Remember it's going to get cold outside. Also think about whether the antenna will be out in the winter.
 Start your antenna project today and take notes. Share your findings on the internet and maybe someone will like your antenna and build one. The Ham Radio Hobby is all about learning, sharing and having fun.

Gizmotchy Beam Antenna



The Gizmotchy Beam Antennas seem to do very well. It does seem that they are suited for more of 6 meters, 2 meters and maybe 10 meters. As my memory serves me they were generally made by Maco. In a 2 meter size it is pretty easy to handle and would not require a heavy duty antenna rotor to turn it. Here are a few videos below of Gizmotchy Antennas for the 11 Meter Band. I am sure they could be used on the 10 Meter Band as well.

So if you feel adventurous try building one for 2 meters and see how it works.

How About A Flag Pole Antenna For The 4th Of July


 First of all I would like to say Happy 4th Of July to everyone out there. Now there are alot of us that live in areas that are not antenna friendly. The reason is that we just don't have the space to put up a huge beam antenna on a nice 40 foot tower. Well one answer to that situation is the Flag Pole Antenna. There are quite a few Ham Radio Operators that disguise their Vertical Ham Antenna as a flag pole and yes with a flag on it. I guess you are showing that you are proud of your country and your getting on the ham radio bands.
 Okay so where do you buy a vertical antenna for this kind of situation. Well you may find a nice vertical on any one of the many ham radio websites on the internet. There is also the possibility of finding a nice vertical antenna on Amazon.com . My other advise would be to search on Ebay, because there are many excellent vertical antennas. Just make sure to check out the reviews before buying anything.
 Once you have the vertical ham antenna the next choice is what are you going to put it in or better yet how are you going to disguise it. Well what pretty much everyone does is place it inside some good heavy duty pvc pipe. Just make sure to paint the pvc pipe to protect it from the uv rays of the sun. I would also recommend using the grey electrical pvc pipe as it has the uv protection. You may have to do some guy roping to give it some good support.
 The other item that should be done is placing some ground radials at the base of the antenna. Most manufacturers will give instructions as too how many and what lengths the wires should be. Remember that the wires do not have to be straight. They can be bent in different ways to fit them in a smaller area. Now you can purchase wire from DX Engineering that is already cut or you can cut it yourself. When laying down the wire I would cut the grass short and use ground pins to hold the wire down. Generally the grass will grow up and hide the wire. You can also get a edge trimmer and dig a trench down a little and bury the wire. I have read that this does not cause a problem and you won't have to worry about wire getting chewed up in the lawn mower.

How About A Collinear Antenna






 So what exactly is a collinear ham antenna ? Here is some information below.
In telecommunications, a collinear antenna array is an array of dipole antennas mounted in such a manner that the corresponding elements of each antenna are parallel and collinear, that is they are located along a common line or axis.
Collinear arrays of dipoles are high gain omnidirectional antennas. A dipole has an omnidirectional radiation pattern when in free space and not influenced by any other conductors in that it radiates equal radio power in all azimuthal directions perpendicular to the antenna, with the signal strength dropping to zero on the antenna axis. The purpose of stacking multiple dipoles in a vertical collinear array is to increase the power radiated in horizontal directions and reduce the power radiated into the sky or down toward the earth, where it is wasted. They radiate vertically polarized radio waves. Theoretically, when stacking idealised lossless dipole antennas in such a fashion, doubling their number will produce double the gain, with an increase of 3.01 dB. In practice, the gain realized will be below this due to imperfect radiation spread and losses.
Collinear dipole arrays are often used as the antennas for base stations for land mobile radio systems that communicate with mobile two-way radios in vehicles, such as police, fire, ambulance, and taxi dispatchers. They are also sometimes used for broadcasting.
Multiple directional antennas mounted vertically separated are referred to as "stacked" and if alongside each other as "bayed".
 Now below is a video I came across and I hope you enjoy it.

Homebrew A Shortwave Antenna


http://rest.ebay.com/epn/v1/find/item.rss?keyword=%28shortwave+radio%2Cshortwave+antenna%2Cdiscone+antenna%29&categoryId1=1500&sortOrder=BestMatch&programid=1&campaignid=5337475659&toolid=10039&listingType1=All&lgeo=1&feedType=rss
 Shortwave Radios are very popular these days. I have a feeling it's due to all the events happening throughout the world. We all just want to keep close tabs on whats happening. Plus if there happens to be an emergency we need some kind of communication with the outside world. So aside from Ham Radio, Shortwave Radio is the next best thing.
 So if you are going to have a shortwave radio you should have a good antenna to go with it. The popular design tends to be a discone antenna design. This may be a little difficult for the homebrewer to build. Now I am not saying it can't be done, but may need some real thinking about the parts involved. So the question is then what will deliver good results and be fairly easy to build ?
  Well it comes down to two designs that I can think of. The first would be maybe a wire dipole of some sort. You may have some traps involved for the various bands and frequencies. Of course we are not transmitting, so power is not really a concern. The second type of shortwave antenna would be in the vertical category. This would obviously not have to be extremely tall, so aluminum tubing would not have to be to expensive. The vertical antenna is going to take up little area and ground radials will not be needed. In fact I would mount it on top of some kind of mast. I might use a telescoping mast, so it's easy to put up or take down.
 Well whatever style of antenna you choose is up to you. My advise is build different styles and determine which one works best for you.

Cushcraft Makes Some Excellent Ham Antennas


 If you are looking to buy a very well made ham antenna I would check out the antennas made by cushcraft. If you check out the reviews at eham.net you will find some pretty good reviews. I have heard some issues with the MA5B beam antennas, but I wonder if it's from going past the specs it's made for. With cushcraft you will find a variety of vertical antennas for various bands as well as beam antennas that cover the different ham bands. Some are in the multiband category and will give access to some of the favorites like the 17 meter or 20 meter band.
 Now you can buy a new antenna or you may find a good deal on a used ham antenna. There are many dealers on the internet that have some good deals. I myself like to browse through Ebay and see whats for sale. If you do go this route I would make sure to read the reviews. If you are not interested in going with cushcraft, there are many different brands and styles of ham antennas to choose from.
 One consideration to deal with is the typical where can I fit this in my yard. If you are blessed with a good amount of property, then you main concern will be your budget. If you are like me then you are limited as to a certain size of ham antenna. Cushcraft does make the smaller beam antennas for the popular bands and then you have the smaller antennas for bands such as the 2 meter band. It all depends where you may want to transmit. So whatever the case may be just make sure to have fun.

Build A Tak-tenna For Small Space Enviroments

 If you are looking for a interesting antenna to build I would look at the Tak-tenna design. I have read some reviews around the internet and it's kind of a mixed bag. Some hams like it and some don't. I think it's one of those things you will just have to try for yourself. If you are interested in buying a tak-tenna or building one click on this link http://www.tak-tenna.com/ .

 This is one of those antennas that can be made of parts easily available at any local hardware store such as lowes or home depot. There are plenty of youtube videos out on the internet where you may get a better understanding of the antenna and how it works.
 If you make one yourself it can be done with pvc pipe and sturdy copper wire of a heavy gauge that will keep it's shape. I would suggest that you read all information out there and use a good swr analyzer to make sure of what it's doing before connecting it to your ham radio. There is no sense in burning up a good transceiver.
 I think if I were building one I may experiment with different sizes and shapes. I may also add another spiral or two just to see what changes.

Build Your Own Vertical Stealth Ham Antenna


Paint it to camouflage it or make a flag pole
 If you are one of those ham radio operators that live in a restricted antenna area or you don't want to upset your neighbors think about a stealth antenna. You can search on youtube and find all kinds of videos where hams are disguising their antennas or putting them in an attic. There are all kinds of antennas you can homebrew and build. That is what the hobby is about, imagining, designing, building and testing. Basically just have some fun and share your project. You never know how you might help someone else that is in the same predicament.
 Alot of this type of stealth antenna is basically a long telescoping fiberglass tube with a wire in it cut for a certain band of frequencies. Then you use a good antenna tuner to tune the system properly so you don't burn up your ham radio. There are plenty of places on the internet where you can purchase the fiberglass tubing or you can buy one off of ebay. Here is a link below where you can click on to find some good deals on these fiberglass telescoping masts. The wire can be bought off ebay or from your local lowes or home depot store.
CLICK HERE FOR Fiberglass Telescoping Masts And Fiberglass Flag Poles

 The other type of vertical stealth antenna and be built out of telescoping aluminum tubing. It can be placed in some heavy duty pvc pipe and disguised as a flagpole. You can even buy some of these fiberglass flag poles to install the aluminum tubing or wire in. Once again ebay is an excellent place to buy these from. Here is a link below where you can search for these items.

Build A Simple J-Pole Antenna


 If your looking for an antenna project to build make it simple. Why not build yourself a J-Pole Antenna for your favorite band and see how well you do. Generally you can build a j-pole antenna out of some common parts from your local hardware store or Lowes or Home Depot. One of the nice features of a J-Pole Antenna is that they can be designed for pretty much any ham radio band. Just remember as you go towards those HF Bands such as 20 meters, 40 meters, 80 meters and 160 meters the antenna will become much larger. Although those high frequencies like 160, 80, 40 and even 20 meters may no be too practical unless you have a really tall place to hang it from.
  A 160 meter J-Pole Antenna may be around 371 feet tall. Now there may be a way to shorten the antenna or make it out of wire and bend it to make it fit. All I can say is you would have to try it and see what the results are. Unfortunately the j-pole antenna was really designed and suited for the bands such as 10 meters, 6 meters, 2 meters and lower. Here is a link to one of the best J-Pole Calculators I have seen http://www.hamuniverse.com/jpole.html . Of course there are many other j-pole antenna calculators on the internet will do a good job . There are also plenty of websites where you can learn more about this type of Ham Antenna.
 If you are building your own j-pole antenna you will find that they are usually made out of copper tubing. People tend to like this material due to the fact that it is easy to solder. Just remember the smaller the antenna the cheaper it will cost. Now if you do not want to build your own from scratch you can buy one from ebay in a kit form that you put together like any new antenna. You will find that prices do vary depending on where you purchase it from. So here is a link you can click on to check out some j-pole antennas.
        J-POLE ANTENNAS FROM EBAY


 I would advise to check out youtube for all kinds of videos on different types of J-Pole Antennas.

Designing And Building A Yagi Antenna

 So where do you start with building a yagi antenna. The first thing I would determine is what ham radio band are you going to be transmitting on. This will determine the size of the yagi antenna you wish to build. For example going from a 6 meter yagi antenna to a 40 meter yagi antenna will be a big size difference. That's not to mention the cost of the materials you are going to use to build the antenna.
 The next step you should take is how do I design this yagi antenna. Well there are many different antenna calculators out on the internet that you can use to determine the lengths of the elements for your antenna. The other choice is how many elements are you thinking of. Obviously the more elements the bigger the antenna, the stronger the materials, the heavier the antenna and where do you fit this monster. If you have the budget and the space I say go for the big monster antenna.
  Another important factor to consider is what are you going to mount this yagi beam antenna on. If it is a small 2 meter or 6 meter antenna you can get away with a metal push up mast such as Rohn makes. Just make sure to support it properly with good guy ropes. I use one and I have it wall mounted to my shed and I use for strong dacron guy ropes. The other choice if it's bigger is to use a antenna tower such as one made by Rohn. Now there are other brands of antenna towers that will provide excellent strength. I used a 40 foot bracketed tower years ago that was riveted. I had it wall mounted to the garage and guy roped as well. It supported my pdl II Antenna for the 11 meter band quite well back in the 70s.
 One other important fact is that this is a directional antenna. In other words you point it in the direction you wish to transmit. So you are going to need a rotator to turn the antenna. There are some that are cheaper that will easily turn a 6 meter or 2 meter antenna. If you are going with a bigger beam antenna I would use one from hygain or Yeasu. You will find that the bigger antenna to support the more expensive it will be. Now I do remember one fellow years ago that used a bicycle crank, sprockets and chain to turn his antenna. I just don't think my wife would like me drilling big holes in the wall.
 If you are building out of aluminum tubing you may check out dx engineering. I would also check out Amazon, but I think your best bet would be Ebay. Smaller yagi antennas for 2 meters, 6 meters or smaller can be made of electrical pvc conduit and good antenna wire. You will find that results will very. I would also make sure you have a good antenna analyzer to use in the building of this yagi antenna. There are also plenty of good books on amazon that will help in the building of an antenna. ARRL Manuals come to mind.
 Always remember to check out your location for power lines and stay safe.

Start Planning A Nice Hex Beam For The Summer


 If you are thinking about a nice antenna project and want a beam for a smaller footprint why not go with a nice hex beam. I have heard many different hams talking about them and they do a nice job. The other nice feature is that they don't take up alot of space. Also they don't have to be placed up too high, so you might get away with a nice 20 foot rohn tower. They always remind me of the old clotheslines that my mother had outside of the house.
Here are a few videos I came across on building a Hex Beam. It should give some good ideas as to building your own Hex Beam Antenna.
             

         

        

  The best advise I can give is look at various videos on the internet and see how various hams design their Hex Beam Antennas. Then take what they did and try to improve on that. Maybe you can think of some different materials to use. Then you can build it and see if it survives your particular environment. If you have any good ideas be sure to leave a comment. Who knows what you say may help someone else figure out a problem they are having.
  Of course if you do not want to build your own hex beam there is nothing wrong with buying a new or used hex beam antenna. I know that DX Engineering has a nice hex beam kit. It can cover a few different frequencies. Also one important feature is that with the light weight of the hex beam it does not take a big heavy duty rotator to turn it. Do a little searching for hex beam antennas on the internet and you will find all kinds of excellent websites on designing and building hex beam antennas. I have found that there are various places where you can buy the center hub as well as the spreaders.

Always be aware of your surroundings and watch out for power lines.
