I chuckled a little over Steve's question only because the guys did forget
to mark which cable was for which antenna. So, Steve, that really wasn't a
stupid question. We checked both antennas out with the antenna analyzer, and
with it, I think we were able to determine which was which, but with the SWR
so high on both of them, it really is a legitimate question to ask. I think
I have determined which coax goes to which antenna, but as I sit here, I am
not 100% certain.
Now, regarding the VHF/UHF dual band vertical, the Jetstream, the Workman,
and the Tram are identical antennas, or at least, the model of the Jetstream
I have is identical to a model with the Workman and the Tram brand names on
them, and so, the problem Mike pointed out could very well be a problem I
have with my Jetstream. That is something we'll definitely check out.

I'll take my chances and ask a dumb question. Any possibility you mixed
up the 2 cables? Wrong antenna going to wrong radio?
