Hi All I have 3 phased verticals for 40 and an inverted "L" for 160. At the base of each of these, I have a pretty extensive radial system. I run a wire from the radials at the base of each antenna t

Standard practice in a multi-tower AM broadcast station is to bond the radials where they intersect each other, and to run an circumferentail arc along the points of bonding. IMO, that is probably ma

Hi all Going to put up a 40/20 (probably use the 40 on 15) multiband vertical for field day. Do they work better with 1/4 radials for each band, or would 1/4 wave radials for 40 work on 20 OK? 73 Tom

If you are talking about elevated radials, they have to be tuned for each band at a 1/4 wave. At the very minimum you need two for each band (on opposite sides of the "circle"). The higher you get th

1/4 wave radials for 40m are 1/2 wave on 20m. If we're talking about a ground-mounted vertical, certainly the 40m radials will work great for 20m. Just put down a lot of them (strive for 20-40 radial

I've used wire as small as 22 AWG for radials. They are still doing a fine job 3 years later. My radials are slightly buried so that the mower doesn't get 'em. I had some 10 AWG I also put in, a mowe

Doug, I have built 2 phased arrays using lengthened Hytowers. The radials are soldered to a ring of nr. 10 wire around the base. The feed line is LDF5-50 hardline. A short piece of bare nr 10 is sold

I would beware of any kind of connection that depends on mechanical pressure for contact, especially if the bus ring is buried in the ground. If soldered, you must use brazing material like silver al

Assuming 1500 watts and a feedpoint impedance of 35 ohms, the feedpoint current is ~6.5 amps. When that current divides among 100 paralleled radials, each radial carries ~65 mA, no big deal for #24.

Sure.. the smaller wire will work. Slightly less well (because the resistance is higher..) AWG14 is roughly 4 times the diameter of AWG26, so the resistance (for RF, depending on frequency) will be 1

As others have pointed out, if you're concerned with the current carrying capabilities #26 is fine especially if you have 60 of them. But, don't neglect to consider the physical aspects. I have 40,00

Indeed... However, once you've got all those wires laid into the soil, some breaks don't actually change the RF properties very much. What you're really doing is effectively improving the soil conduc
