If the radials have a good chance be being submerged in fresh water, I would consider elevating the radials. Had an experience here where my 40 radials on each of my 4 square verticals were often tim
Topbanders Thanks to all who responded I received a lot of good advice and will be taking it. Specifically, the advice to bury the hardline rather than elevate it. Some brought up the idea of my grou

I feel it more appropriate to say that the function of ground-mounted radials is to harvest the radiation from a vertical antenna that splashes on the ground and return it to the feed point for recyc
Recycling signals at the feedpoint sounds more like a mismatch swr situation. The ground radials form half of the antenna, and that radiation from ground, in phase with the vertical radiation determi
A counterpoise is what we do when the full size of a double-ended antenna, dipole, OCF, etc is too large for us to build, maintain, etc. Very simply, we want to jam the energy from the shield of our

Inspect your feedline you plan to use (sounds like it is Heliax) and make sure the jacket is undamaged. If it is okay, you can bury it or just lay it on the ground and it won't matter if water covers
Guy (K2AV) - I really liked your explanation about the function of a radial field on a 160m vertical . . . and how the radials don't actually radiate. But I've often thought about the other extreme .

Hi, Roger It sure seems like a lot of confusion arises when folks attempt concise electrical and mathematical thoughts and calculations using words with very broad and fuzzy definitions. Words like r
Roger, Take a look at this. I am thinking of building one this summer and hang it from a tall tree. https://www.yccc.org/Articles/double_l.htm 73 Mark N1UK G3ZZM But I've often thought about the oth
