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.
