That's one of the reason I like the Outbacker. Besides it's made in
Oz...

I've never been impressed by the Outbackers, nothing but hookup wire
wrapped around a fiberglass rod with plastic taps in the continuously
loaded coil whip. It's too short for a good radiation pattern below 20
meters with way too much loading and you can't put any real RF power to it
which will destroy the hookup wire it's made of. "Homebrew" comes to mind
under the shrink wrap exterior.

Some have commented they didn't like having to go out to change the taps.
I'm curious how they keep the salt out of the little holes from corroding
it all up.

The longest screwdriver antennas would make a MUCH more efficient HF
tunable antenna for all the bands as they have continuous coverage if we
could figure out how to keep from drowning their coils in seawater....

KJ7U's screwdriver with the rubber boot looks very promising for marine
use....

Tarheel says theirs is for marine use.

The key to all these antennas is they use a LARGE, EFFICIENT, center-loaded
coil with a continuous tap that allows you, or an autotuner, to put the
tuning of this antenna EXACTLY on your frequency, not "close enough" like
an outbacker. ANY frequency as the coil is continously tuned, not banded.

The idea of tuning by remote control, from the nav station for instance, is
much nicer than having to go out to the outbacker in the weather on the
stern to fool around with that stupid tap.....

The longer the whip on top of it...the better because it reduces the amount
of loading coil necessary to tune it.....
