Will build a GH antenna
What a godsend this antenna research forum is!! One of my applications is in the middle of Minnesota, over 100 miles from any major city (Fargo, Duluth, Twin Cities) having powerful transmitters. As a result, the transmitters available to me by antenna.org are mostly low power repeaters, or the like, only a couple of which will be digital, requiring antenna performance of violet to yellow and scattered from 20 deg magnetic to 92 deg magnetic, over a 12 mile to 48 mile range. I may even have to get one transmitter at 280 degrees magnetic off the antenna backside at 13 miles. After much looking, the only thing that came close to my needs was maybe the CM4221 with an amp since I need the wide beam width (~30+ deg) The CM4228 has more gain but narrower beam width, so that wouldn't do.
Then I stumbled onto this forum/website and I'm totally obsessed with reading the GH design and construction details. This is the solution that will save my bacon!! The only question now is which design. So far I'm gravitating to the second gen GH6 for its simplicity. I have an old tv antenna I've scavenged the aluminum elements from for the co-linear rods; don't much like the huge screen support (it gets a bit windy at times here), plus I probably will need some backside pickup. I'm not a construction weenie so will not have much to contribute - just sit back and absorb it all.
BTW, I hope your copyright is ironclad!! Thanks a lot to 300ohm, et. al..
