Fine on receive, but a bit limited on transmit. You might do better to get rid of the loop and just use the sense aerial... Cheers, Jim Moritz 73 de M0BMU

Hello Steve and Jay, I simulated a 15m high / 30m long loop at 1m above ground (Er=5, S=0.1mS/m) using MMAMA. Results were : The loop is actually fairly omnidirectional - just not at 0 degrees elevat

Steve The loop is actually fairly omnidirectional - just not at 0 degrees elevation. As you move up from 0 degrees elevation the pattern starts to "fill in" nicely in the direction of the "nulls". No

Steve, You can make a loop omnidirectional by mounting it horizontal. That makes it respond to the vertically polarized component of the EM field, so of no use on LF. Another way is to use two loops

Steve, As far as I know one can not make a single loop omnidirectional. But a combination of 2 loop (under a 90 degrees angle, a kind of "crossed loops") may have an almost omnidirectional pattern. 7

Gee, Mal, if all of us follow this general statement of yours, you will have few new stations to contact (as you were complaining about only a month ago). All debates aside, at least the loop allows
