Tight bends in the coax?

Very possibly. The original installation was very tight bends, both coming
out of the mast and into the antenna. OTOH, the antenna to the helm is also
very tightly bent (I didn't like it after the installation by my electrical
guy during our original installation, as well as the splash shield being
mounted UP - but it was done, and there's not enough length to make it
right), and it works fine.

All that said, I've concluded that, regardless of my shortly-to-be-tried
checking with a different antenna up top, I'm going to spring for a new
antenna and cable. This thread and others in different venues have me homing
in on the best cable I can buy (no sense in doing it wrong, for the sake of
a few bux, in what should be the last time it's fiddled with!), which, with
a new whip (don't know that we'll ever have to deal with a bridge again in
our ownership, but I'd rather not have to replace a lovely stick if we do,
not to mention that I expect most sticks would be a different mount than the
259 UHF connector I went to the trouble to install on my bracket), should
put the matter to rest.

When I DO replace it, I'll make sure of the proper length/radius of turns so
that it's not an issue for the future. I rather like another's comment
about some expensive stuff which is both thinner and lighter, but notably
better for the application. Once I have a proper reference number, I'll
hunt it down and lay it in when I'm back ashore.

In the meantime, I'll also do the check suggested by someone else in the
thread about checking out the antenna which was up there, it being out,
now...

Stay tuned (pardon the expression) :{))

finally ended up buying some expensive military grade low loss co-ax.
It was about a buck a foot back in the '80s but it was great stuff
with teflon insulation and silver plated conductors. That was the
end of my cable problems and we had the best VHF reception I'd ever
seen.

Got a source/grade suggestion for something like that?

Sounds good to me...

I've seen it at West Marine. The key phrase is "Low Loss" cable.

Here's one source online with several choices -

You have to be careful with those cables in a marine application.
They will soak up salt air like a sponge if given any opportunity at
all and will end up worthless. The RG142/U has a solid teflon
insulator which is quite moisture resistant and the double silver
plated shield keeps the signal inside the cable where it belongs. It
is MIL Spec rated for a reason.

I believe it was Belden RG142/U. Unfortunately it is now about
$2.25/ft from RF Parts:

The good news is that they sell it by the foot. I had to buy a 100 ft
spool when I got mine.

Maybe you can find some on EBAY.
