MY ISSUE: Even though the HexBeam's 20m VSWR measurements appear quite
normal made
directly at its shack feedline connector using the 259B meter, they are
VERY DIFFERENT when
measured through a Delta-4 switch. The GAP antenna's VSWR's are very
normal-looking when
made through its
I agree with swapping the two switches to see of problem is on both. Is
there any other grounding to the switch chassis?
Other than that, are you using same length coax jumpers, (same jumpers) and
just subbing antennas? I have seen many problems move with jumpers, even
those you think are good
I looked at the HEX BEAM web site to see if anything special about the feed.
Sounds like it is a simple 50 ohm coax connection. However, compact
antennas have intense near field, so if there is coupling back to shack thru
its gain direction you may have a weird case going.
Keep us informed of
I would put a balun or choke at the feedpoint of the HexBeam for
starters... sounds like
rf on the shield might be causing problems.
