I'm having a repeated weird problem with compression F connectors on
quad-shield RG6. When I connect a short length (say 4 feet) of cable to
my MFJ-259B, I would expect R>650. Instead, when I wiggle the coax,
occasionally I see the display change to R=0 and X= several hundred ohms
at 1.8 MHz. This makes no sense to me - the R implies ashort, but
where's all the X coming from? The problem seems to vary with the same
connector and different PL-259 to F adapters, which makes me wonder what
might be happening inside the adapters, but I can't imagine anything
producing this result. I have also been unsuccessful in detecting a
short using a simple DC multimeter.
I;'m wondering if I should go through my RX antennas and replace all the
F connectors and particularly the F to 259 adapters with something else,
but what? BNCs?
Anyone have any wisdom?
