Well I just finished hanging my new G5RV yesterday and I have already had some impressive results when comparing my long wire to the G5RV. After I first connected the antenna to my K2 (7109 ) I thought something was wrong. Then I figured out the I'm not hearing the noise that the long wire antenna picked up. I was working a net on 80 meters this morning and when switching back and forth between the long wire and the G5RV. I could not pick up the net on the long wire but with the G5RV I could. I don't know if my abilities in being able to receive translates to a a better radiated signal but I don't see how it can't.
The S meter reading on the long wire this morning ( 80m) was S9+10 and the G5RV noise level was an S4 so I am picking up signals I was missing before.
Anyhow I'm stretching the limits of the home owners association with the wires hanging from the trees but it's pretty stealthy and since I'm on 3 acres I don't think anybody cares.
