This is my first post on TowerTalk. I'm about to install 20 radials for a Hi-Gain AV-18HT and Hi-Gain recommends burying the Radial ends if installing less than 60 radials. I called Hi-Gain and asked

I have used HyTowers and home brew verticals for many years and have never buried the ends. Just install as many radials as you can and it will work well. GL and 73, Rod/w7zrc This is my first post o
There is ZERO reason for radials making electrical contact with the earth. Their function is to provide return current for the antenna IN PLACE OF the earth, which is very lossy (that is, it wastes t
This might be one of those times when you do not need to follow the manufacturer's instructions. You may wish to bury the wires to keep them out of the way but it is not necessary. I have never heard

I have a mish-mash of long, short, insulated, bare, solid, stranded, thick, thin, on ground and below ground radials for 80 and 160 that has accumulated over the years. It doesn't matter. What matter
Well said Steve., although "as long as you can" has reasonable limits as to what's optimal for a given frequency and overall radial count. N6LF's article should be first stop for anyone serious about
YES! I assume that K3LC Al's conclusions on optimal length vs. count would match up roughly with N6LF's. The key point here is that from getting the best bang for your radial investment, there's bot
The underlying elephant in the room, borne out buy all the tables in the article, is that the conductivity of the soil is much more important than the dimensions of the radials. If you have really po

I have folder on my hard drive called "Severns." In it, I have almost every antenna article Rudy has written. I say "almost" because he is a prolific experimenter and writer and it's hard to keep
About ten years ago, I did the experiment of modeling a pair of radials cut to a free-space resonance, starting with them as close as NEC2 would allow it, and raising them in small increments to seve
I expect I'm an outlier, in a couple of respects. I have 30 x 70-foot radials on the ground under my 160M inverted L. I'm sure this will bother people, but I made up the radials from a spool of abo
The only downside is mechanical -- larger wire may be a bit less subject to damage. 73, Jim K9YC _______________________________________________ _______________________________________________ TowerT
I'm fairly comfortable in that respect - the taxpayers who paid for this stuff got a darned sturdy product. It's a battle even to strip. 73, Pete N4ZR Check out the new Reverse Beacon Network web se

That sounds like a neat experiment and AutoEZ's "Resonate" button makes it easy to automatically adjust the length of the radial pair (modeled as a dipole) for resonance as the height above ground is

We have about 4 foot snow drifts and it's COLD but fortunately the snow is easy to shovel. hi Shortly, I plan on erecting the Hi-Gain AV-18HT Vertical and for now , laying 10 radials in the snow. I'm
