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....

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.....

Don't knock it til you try it! I would agree that the taps present a
problem in the maritime environment (possibly) but many hams down under
use the outbacker and swear by them. So unless you have first hand
experience using them your feelings count for nothing! Too many people
make judgements about products without trying them! No first hand
experience value of opinion = 0!

I have run both the outbacker and Large Shakespeare whip on 20 meters
marine.

The outbacker was a test as a backup on a boat with a back stay antenna .

Neither antenna is in the same class as a backstay. The outbacker was
better than the whip...though the boat with the whip may well have had
ground problems.

Switching the outbacker and the backstay you could here the stations vanish.
It was still possible to work the states from off Baja but you needed
somebody on the state end with real good equipment.

After playing controller on Pac Sea Net for a few years the boats that get
out well almost exclusively have backstay antennas.

There's a new QSL on Lionheart's nav station. Braggin' rights...(c;

Japan from Charleston on 20 meters, 14.208 Mhz. He was runnin' 100W. I
was running 150W. Backstay tuned with Icom AT-130 is 55' to the insulator.
Next time the mast is serviced, two new insulators are going to be
installed, one on each end of the triattic and a new cable installed from
the bottom of the top backstay insulator to the forward end of the
triattic, making it even longer with a horizontal top component, more like
a ship.

Longer is better, especially below 10 Mhz.

I'd take my modified, 650 watt TenTec Hercules II solid state linear on
trips in the boat, but the tuner is maxed out. POWER is our FRIEND....

It only draws 120A at 650W keydown on RTTY...(c;

Big deal. I have worked Australia and the south pacific on 20M with my 23'
whip.

It is consistency that matters. In general successful net operators
generally use beams, power and elevation. Even at that there comes the day
when you are still shut out. The nets work because they have multiple
operators thousands of miles apart.

You need to be able to make contact when you want or need to. Not when
conditions are perfect. I can often work Japan when conditions are
right..but what I really want is to work the S. Pacific well almost every
night.

Power is over-rated. You have to hear the other station. Does no good to
only be heard.

Whips are relatively effective on the large ships...but they have the
wonderful ground systems.

Outbackers and whips are simply compromises...nothing works like length.
