Comm Antenna, Part 2

While researching home-made aviation antennas, I came across this article on the internet: http://www.eaa.org/lightplaneworld/articles/InvVeeAntenna4ULsREV.pdf. Again, it is a balanced antenna being fed with an unbalanced feedline, but rather than using ferrite beads to choke off excess RF energy, it uses a BALUN, so I thought I'd give it a try. I used a piece of 1/8-inch plywood instead of nylon for the center mounting block, but otherwise, construction was pretty much identical. This one came out much better on the SWR meter, and I probably would have lived with it, but as the saying goes, "The enemy of good enough is better still!"
