Thanks Larry. The boat in question is a 20ft center console. No top,
bimini or otherwise.
The existing antenna is the standard antenna I've seen on pleasure
boating since childhood. Fiberglass antenna. 6ft would be about right,
with the plastic quick release for lowering and raising.

@newsfe24.lga:

The VHF antenna is broken/snapped. It's still together but not much.
It's an old Archer fiberglass antenna on a swivel mount. Parents duct
taped it to hold it. Is it still good or does the fact that it's
snapped
mean that its functionality is in some way hampered.
Trying to run a knew antenna would be a nightmare. No deck access and
the cable is run under the deck, though I could tie the new one to it
and pull it thru hopefully.
Real concern is that the swivel mount seems to be part of the
antenna.
It's an aluminum boat so don't want to drill new holes to accommodate
and new antenna. If the antenna itself could be replaced outside of
the
mount, that would be great.
Thanks.

How high is it? If it's above your head, get a Metz Manta 6 with the
little angle bracket:
http://www.metzcommunication.com/manta6.htm
It requires no ground or ground plane. You can talk 15 miles holding
it
in your hand and it's a perfect match. It's 34" long, a 1/2 wave,
end-
fed. If you ever destroy it, I don't want to go boating with you.
One
was mounted by an existing bolt under a holddown handle on my jetboat
near the bow and flogged to death for years with no failures, at all.
It's warranteed for life! The CG has them on all their boats.

Just cut the cable as close to the old antenna base as you can get and
put a PL-259 male UHF connector on it. The Metz has the mating
stainless
SO-239 UHF female connector on the bottom of it. Use a piece of
shrink
tubing filled with RTV to seal it from the sea to cover both
connectors
for life. Metz never rusts.

A better way to mount it, as it requires no groundplane, is to drill a
3/4" hole on top of some horizontal surface and simply bolt the Metz
to
it, as high as possible. The connectors will be inside the boat, out
of
the weather. So small, you'll hardly notice it's there. It doesn't
require tilting if you trailer, which is wonderful.

At the same height with 25W applied, we've never been able to tell any
difference in its range to the horizon between this and the big, tall,
so-called "high gain" fiberglass whips 6' long. The horizon is the
horizon on VHF radio. Only ALTITUDE makes that horizon further out.

Don't forget to tighten the whip nut as you complete installation
because
you'll lose the whip if you don't.
