Anyone - Is the performance of the 5' antenna seriously below that of the
8'er?



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.

Great company, too.

This guy has it on sale:

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?


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.
