Messed around with the radials today. I pulled them off the fence, and coiled them up to 25', and saw the VSWR curves improve. I kept doing it until I couldn't reach any higher to cut them, and they wound up being about 6'~7' long, hanging straight down from the ground connection (coax shield), and tie wrapped to the mast.
This might be "as good as
it gets" with this antenna, in this installation. The BuddiStick still
works better on 20 Meters, so I'm hoping the CommTek 20 Meter aluminum
tubing vertical will be as good.
This isn't 100% usable with the FT-1000D, as the VSWR in the 75 Meter band (3.5~4.0MHz) is still outside of the range the radio.
And I'm feeling somewhat better, but still sneezing with a very runny nose.....
