I'm thinking of taking advantage of a very sturdy concrete fencepost and a long wooden fence to put up a 80+160 "fan vertical" with 2 elevated radials each. The radials would be stood off from the wooden fence using something sensible like electric fence parts. The fence itself is about 7 feet high. I was thinking about having radials at a height of something like 5 feet above ground and then either a fiberglass or PVC support for each vertical element which I plan to linear-load. One person who I know has an elevated vertical for 160 has his 2 radials about 25 feet up - he thought my 5 foot elevation might be too low. Is he right? In this famous reference from N6LF: https://rudys.typepad.com/files/elevated-ground-systems-article-final-version.pdf A very helpful plot is this one, which shows dB gain (versus something) as a function of height for a 4 radial elevated vertical operating at 7.2 MHz: So at 6 inches off the ground, you lose a dB at 40m. Scaling naively, that means at 2 feet on 160m you would lose a dB. Am I right in expecting that at 4-5 feet AGL my linear-loaded vertical would work much better than a ground mounted version (referring to ground losses)? I expect to find a very low radiation resistance for each of these fan verticals (ballpark 30 foot height), so depending on what I measure as the R value for each, I would use a (1:4 or 1:N ?) balun at the base of each. Safety: there are no small children or medium sized animals in this closed-off back yard. Thoughts please?
