I have a small yard - a very small yard. I use an 80M loop and it takes up 3/4 of my yard. Needless to say, I do not have space for 120 radials 100 feet long. I have height - a lot of tall trees. My
Scott: Tying the feedline leads from your loop together is supposed to work. But keep in mind that it is this parallel pair of wires that does most of the radiating - they form a vertical antenna, so
I will try that...tying the ends together. As it stands now, connecting the loop to the tuner in normal fashion, I am able to get a 3:1 match. So there is hope. I also use a 80M vertical with a capac
Scott: Yes, you can use magnet wire if it's available to you. But its insulation layer will probably scuff away after a year or two and the underlying wire will begin to corrode and open up on you. I
I guess I disagree and feel magnet wire is too fine to work as ground radials. I also recommend the THHN for the same reasons Gene does but do not feel the magnet wire is strong enough. People and la
Scott, I have a small yard too and I do fine on 160/80 with 100W. My radials are #18 stranded bare wire and are laid out like this: http://n3ox.net/projects/flag/layout_lg.jpg _______________________
Magnetic wire is available in all sized. If you try to put down a #30 you might not find it after some time but #18 and up should stay for some time. (I have some #8 and that will last for a long tim
Dan: Do you have any issues with interaction or funky pattern distortion that close to your flag? Scott Scott, I have a small yard too and I do fine on 160/80 with 100W. My radials are #18 stranded b
Just an academic question.. how would one know if the pattern is distorted? I've given quite a lot of thought and experimentation to figuring a good way to measure HF antenna patterns as installed (f
I am also on a small lot in a city with a 1 wavelength 80 m. horizontal loop. Actually mine is 1 w/l at around 4 mhz so where I operate it's really more like .8 or .9 w/l. my lot is 50 x 100 feet. I
I like that idea. I was concerned that I would have issues with changing the loop. I really like the loop, especially for working local contacts. It works very well for 80M and 40M on Sweepstakes. Th
How would I know if it's distorted? Easy in azimuth with a rotatable antenna. 1843.2 kHz TTL can oscillator driving a six foot whip against a short ground spike stuck out along a riverbank about a w
If you have a support for the loop that is 560 feet tall then you don't need an inverted L; you can at the least put up a 1/4 w. vertical with no horizontal part at all. I am not sure what is limitin
Really interesting radial layout, Dan. I have a similar situation, and wonder whether you did any before-after testing - measurements regarding adding the longer radials that extend along the side ya
very cool.. But that's only one bearing relative to the antenna site. If you had, for instance, a huge mile high metal wall on one side of the property (opposite the direction to your pinger), your p
The location of my tallest tree is "just on" my property line. The property slopes strongly front to back. Because of the location of the antenna, to obtain a symmetrical field, I would have to go in
I think so. Fellers with multiple verticals, and/or nearby towers, often see such interaction between same. How much... and whether it would be all bad... I don't know. I suppose it would be a mixed

Maybe you could use your 80 meter vertical as part of a 160 meter inverted L. Some folks use a coaxial trap about 50 ft. up the antenna to block 80 meters, then feed a long line out from there. I hav
Wilson.... did you try a "preselector" with the antenna analyzer like we SWL do with our lower end receivers? Why not try it? If you don't have one, maybe I can loan you one of mine for the test. Wor
