None whatsoever. I got to the horizon on a Metz Manta 6 halfwave at butt
level in a Sea Rayder jetboat all the time.

VHF only goes to the horizon, line of sight. To get further, you must
extend the horizon with ALTITUDE. 5' to 8' means nothing.

Screw a bunch of sun-destroyed fiberglass rods. The Metz is guaranteed for
life unless you lose the whip out of it. All the USCGs boats use the Metz,
a testimonial to its rugged construction. Completely self-contained. No
ground plane required. It'll work the horizon holding it in your hand.

Thanks for the tip, Larry.

Another question: Most antennae seem to come with about 20 feet of wire.
Mounted on a console with the radio right there, I could get by with about
3 feet of wire. Is all the extra wire necessary?

No. You can cut the wire to the length you need.

Not technically true, but probably doesn't matter in this application.
Performance of the radio is going to be marginal anyway. He'd be better off
coiling up the cable in a relatively large coil (not tight) for best
performance. It's length *does* affect proper antenna loading.

wow, I guess Horizon and my installer knew what they were talking about.

And that's a *loaded* statement which gets debated in some circles
almost as much as "which boat is the best".

In theory the length of the coax does not matter, but that assumes a
perfect match with a SWR (Standing Wave Ratio) of 1:1. In practice an
SWR of 1.5:1 is generally good enough to ignore feed line length. This
discussion quickly gets very technical and into some very esoteric
transmission line theory.

Someone else mentioned the issue of being able to properly install a
coax connector which is also important. If you do not have the tools
or expertise, it is better to leave the coax uncut, or hire a
professional radio guy to do the job right.

No, but I was told that unless you know someone who can do a new
connection as good as the old connection, (which I was told will not be
done by the average DIY or boat mechanic) I was told it was better to
just wind it into a ring use some velcro to keep it out of the way.

Well, I know (?) Shortwave! He could probably tell me what to do.

Shortwave doesn't know sh*t.

On the serious side, it isn't knowing how to do it, it is having the
skills to be able to do it well. Now if you fly SWF down, he might be
able to splice it for you. But it might be cheaper to buy a short ant.

I can't remember who told me this, or where I read it, but I think it
was in the instructions that came with my Horizon VHF. The question I
asked my installer when I heard this, was there any problem to wind it
up. I was told no, but they said a bad splice job can make a good VHF
worthless.

Needless to say, this will prompt a long discussion on the correct way
to splice or how stupid it is to splice an ant. wire

Yes - it's part of the loading for the antenna. There are forumlas
where you can cut the wire length down, but the problem is reattaching
the connector. You can use a mechanical connector, but they aren't
really a good idea.

Just roll it up and tuck it away.

SWF,
I was trying to get you airfare down to Baltimore and you blew it.
