Hi Jerry
OK, now were getting somewhere. I'm really not too concerned if the meter
is a good one or not. The swr in the shack meter agrees with what the
analyzer says.
Without all the meter readings etc, if I did have a SWR of 3:1 with a 50 ohm
cable, that would mean the impedance at the feedpoint could be 16.6 ohms or
it would be 150 ohms. I can't figure why it would be clear down to 16.6 as
I know the radials are in good shape. I trimmed all the ends and
resoldered them so they would be fresh. Would the presence of the 80 meter
dipole about 68 feet away from the point where the antenna goes from
horizontal to vertical mess it up that bad.
