The Quad Antenna Does An Excellent Job


 From my earliest days in the 11 meter band I had my PDL II antenna, which was a quad antenna. It did an excellent job back in those days. Now in my Ham Radio Hobby I am working on a 6 meter quad antenna. If you are interested you can see what I am doing on my other blog at http://thehamshackshop.blogspot.com/2015/02/homebrew-6-meter-cubical-quad-antenna.html 
Yes it is still a work in progress and maybe since it a little cooler I may do more with it. I guess it's one of those things in life where we get distracted and follow a path.
 http://www.w8ji.com/quad_cubical_quad.htm or http://www.dxzone.com/catalog/Antennas/Quad/ . There are plenty of other websites with lots of useful information that can help in your design of a cubical quad antenna. Just remember if you use electrical pvc conduit pipe or just pvc pipe the higher the frequency band you go the larger and heavier the antenna will be.
Okay back to the subject of the Quad Antenna. If you are interested in quad antennas here is a link to some interesting information
 If you are looking for some excellent videos on a fellow Ham Radio Operator and his Cubical Quad Antenna Project follow this link https://youtu.be/ktrfw4329aM . There are quite a few videos in this project, but they provide some excellent information. There are other videos on youtube as well that will help. One useful tool is the antenna calculator for quad antennas. Here are a few links to some quad antenna calculators http://www.qsl.net/yt1vp/CUBICAL%20QUAD%20ANTENNA%20CALCULATOR.htm , http://www2.mmae.ucf.edu/~ssd/ham/quadcalc.html and http://www.csgnetwork.com/antennae5q2calc.html . So if you are interested in building a cubical quad antenna for any Ham Radio Band remember to have fun.

Build Yourself A Vertical Ham Antenna


 Are you one of us Ham Radio Operators that does not have a lot of room for big antennas. Well maybe you could fit a nice tall vertical antenna in you back yard. There are plenty of nice Vertical Ham Antennas that you can buy brand new if you choose. Some of the popular brands are MFJ, S9, Cushcraft, Hygain, Hustler and Zero Five. All of these are excellent ham antennas in the vertical category. The only issue is that some are a little on the expensive side. If you choose this route that's okay there is nothing wrong with buying new.
 Now if you want to build your own vertical ham antenna there are plenty of ways to do it. If you look at the S9 Vertical Antenna it is basically a long given length of wire stretched out in a vertical fiberglass tube. So why not take that and improvise with your own ideas. For example I have seen many hams where they used some pvc pipe to make the tube. If I were doing this I would use the grey electrical conduit for its UV Protectiveness . Just remember that any PVC Tube gets weaker at longer lengths especially when standing up vertical. An idea would be to stand it up using a tree as a support. You could use Dacron Guy Rope to keep it steady. One idea may be to insert some dowel rod inside the tube for some added strength and rigidity.

             
  For this type of vertical antenna you will need some kind of ground plane or counterpoise. Antennas like the S9 use the coax cable as a counterpoise. This could cause some rf problems and a balun will be needed to help. You can always build one of the ugly baluns, which are very simple to make. It is simply so many turns of coax cable around a pvc tube. I have seen some hams just wrap it together with tie wraps making sure the two ends of the cable do not touch each other. That is why I use a 3 or 4 inch diameter of pvc pipe. There are plenty of websites on the internet for making an ugly balun. Here is a link to some excellent information on making an ugly balun http://www.hamuniverse.com/balun.html .
 If you are laying out ground radials they can be in various patterns. Also I would start out with 4 or 5 20 foot wire radials and add more if needed for better results. There will come a certain amount when it won't make much difference.
 As far as supplies go most things can be purchased at lowes or home depot. Heavy gauge wire can be used, but antenna wire from DX Engineering or maybe from Ebay would be preferred. Basically it would hold up much better with the elements outside. Another idea for the vertical tube is a Telescoping Fiberglass Mast . Just be aware that some could be expensive. There are some flagpole masts that are not too expensive. I have also seen that mfj is selling some push up masts as well as Max Gain Systems.

Build A Double Bazooka Ham Antenna

 Here is an interesting ham antenna you could build. It's called a Double Bazooka Antenna. If you are looking for some reviews on the Double Bazooka Antenna check out http://www.eham.net/reviews/ . Here is another link with some excellent information on the Double Bazooka Antenna http://www.k3dav.com/buildadoublebazookaant.htm . If you are looking for a calculator for the double bazooka check out this link http://www.westmountainradio.com/antenna_calculator_bazooka.php . Below is a video I came across on youtube and there are other videos out there on the internet.
