Just a note, I have used the AX1 antenna with a tripod in a National Park site where antenna restrictions occur (i.e. no wires in trees and no ground stakes). Try as I might I can not get it to be resonant on 20 meters;although it is supposed to be possible. The T1 ATU seems to have trouble establishing a match. The KX2 may have more capability to match the antenna. I use a QRP 5w CW inly radio with the whip.?
That said both of my attempts for a POTA activation have been successful. Most distant contact was around 850 miles.?
If anyone has suggestions on reaching resonance with the AX1 on 20M please contact me.?
Good Luck!
