Archived from groups: rec>boats>electronics (more info?)

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.
John

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.

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.

ps I prefer to have an antenna that can be lowered.
Yes, boat is trailered.

The radio system on my Sea Rayder little 16' jetboat was an Icom M59 into
the Metz up forward just above the gunwale....about 2' off the water. I
could talk to boats I couldn't see over the visual horizon...at the radio
horizon.

Go for it. You don't need that big folddown monster. Mount the antenna
on the top of the console just behind the little windscreen, but not
against or near any other metal parts like window framing or other
electronics the RF may tear up, like your sonar or GPS. They work fine.
Metz also has a standard mounting kit that will mount the metz on a fold-
down mast screwed right into where your old antenna was screwed in. The
coax is inside of it. That gets it up a ways above the damned RF racket
the outboards are making....(d^Smile

Thanks Larry. I ordered it right after posting my messages.

Excellent. It doesn't look impressive, but works very well. There a 2
meter ham radio version stuck to the top of my truck that's outlasted about
6 vehicles. Works great.
