I am recovering from spine surgery and have been thinking about a Very very very large loop antenna as most of us have ! Is a formula available for this that would incorporate the height above ground
Can't answer your question, John, but was wondering where you would find the 200+ supports to hold up the loop? 73 Don N8DE _______________________________________________ ___________________________
!!!!!!!!!! The pattern is remarkably weird. I tried a square loop at 50 feet above "average" ground on 160m and 80m, fed in the middle of one side. http://n3ox.net/files/hugeloop.jpg It's basically
That radiation pattern may look weird for an antenna but it looks amazingly like a Roadrunner in flight. It's the state bird of New Mexico but we often see them here in Arizona as well, and since the
I can see no advantage in an antenna like that - even the copper loss begins to be significant. The pattern is bad enough on 160m and 80m; I can't model it on higher frequency bands because I exceed
It is a little interesting that at 50 foot height, the pattern of a single 6600 foot center-fed wire has a single clean lobe on axis and the low angle gain is quite high. Might be uselessly narrow be
I've seen a great many roadrunners in flight but only a very small number of them were flying north, true or otherwise, although most do seem to fly pretty much in a straight line. Assuming that I ca
I'm still curious why anyone would want to put up a loop with five miles of wire in it. What was the intended purpose? VLF or something? I'm also curious how it was planned to be supported. Even with
I am still curious how you are going to keep the static build-up discharged? Tom - W4BQF I'm still curious why anyone would want to put up a loop with five miles of wire in it. What was the intended
There you go, you blew his cover. What he is actually planning to do is run the antenna parallel to some high tension power lines and get free electricity. If the power company gets suspicious, he ju
That sounds like one of the old country, open wire telephone lines...or a fence. 73 Roger (K8RI) _______________________________________________ _______________________________________________ TowerT

There was a VP2M back in the early 1970's who had a large loop but it was merely 1500 feet on a side. He was very loud on both 15 and 20. He ran Europe on 20 with ease. Dave W7FB (Ex W0MHS) also know
