Thanks, Brian--

It's a whip, with a cylindrical fixture at the base about 1-2 inches in
diameter and maybe 1 foot high. Is this a "coupler?" If so, I'd be happy
to put it in anyone's hands who could use it. Do you know of anyone?

Cheers,

Dick B.

LORAN antennas come in two flavors - a whip or a long wire.
These low frequency signals at 200kHz often went through 'couplers'
then a coax to a loran connector.

The copuler is often in demand, because lorans tends to be sold
without them.
If the antenna is a whip, it may be rather long for a VHF antenna
which is about 20 inches for a 150MHz 1/4 wave.
A CB antenna is about 60 inches for a 1/4 wave at 50 MHz.

A wire antenna can be useful for HF communications. - the longer the
better.

It sounds like a loading coil, which if properly tapped will offer
close to the 50 ohm match the receiver wants.

Thanks for the information, Larry. (There ARE some electronic wizards
around here!) If you know of anyone who could possibly use this antenna,
I'd be happy to send it to them for the cost of shipping. Otherwise I might
well use if for a flagstaff.

Cheers,

Dick

Nope..Almost certainly an active preamp. Not a loading coil. See Me
comment. Jim

Probably both....at 100Khz, Loran C's freq, a 1/4 wavelength whip is 2,460'
high....Probably wouldn't survive going under those big powerlines...(c;

Nope...does not compute. A loading coil of a sort might be a component on a
preamp board. But a preamp board is never a component on a loading coil.

If some version of a balun or loading coil is present it will be narrow
tuned and unsuited for use at other than the LORAN frequency.

And you know better. Don't play technical one up for the hell of it.

eBay still shows a steady stream of Lorans for sale - often without
couplers. Put it there
