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
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
re-soldered them so they would be fresh. Would the presence of the 80 meter
dipole about 6-8 feet away from the point where the antenna goes from
horizontal to vertical mess it up that bad.
