I discovered that 7. FM radio stations run circular polarization. Home receivers are usually horizontal while mobiles are vertical. After looking up the types of antennas they use, I came up with two designs. The first has as much gain as a QHA but is much easier to build. I recommend this to new builders as small errors will not greatly affect performance. The QHA can be rendered useless by errors of only a few millimeters. The FM station antennas use a round horizontal element which is difficult to scale and build. By changing the elements to square, the antenna scales from 5. The second antenna is even simpler, consisting of only two bowed elements. While not as good as the first, it still shows promise and anybody could build it. Although originally designed for 1. The omniquad V2 corrected is a very simple but excellent standby vertical antenna. Ive built many over the years but just got around to making up a program. The main advantage is the extreme bandwidth. Make all the dimensional errors you want, and it will still work. You can use wire or tubing. A broom handle ,some 14 dowels and under 1. There is very little gain or pattern difference between the 3 and 4 sided versions but the 4 sided version does give a better match. It can even be used as a desk top antenna. The log periodic antenna is the ultimate broadband beam. It can provide high gain on a single band or moderate gain on multiple bands. On vhf you can easily design a single feed 2 and 6 meter antenna. On hf the size and element diameters are usually a drawback. Wire versions are usually the answer. Although 4 bands is usually stretching it, dont be afraid to try more. I had an inverted T loaded 1. It covered an acre ,was 1. The 12 mile of wire looked like a suspension bridge. The neighbours are still cautious to talk to me and the XYL doesnt want to discuss it. Manufacturer of amateur radio and shortwave accessories. Manuals and reviews. This was my first AO10 antenna.
