I was going to take my old loran antenna off the mount and remove the
antenna and clean the coupler body. Found the antenna is "frozen" in
place.
Probably corrosion of one type or another. I've been squirting WD-40 at
the
antenna base, hoping it would get down into the threaded area to loosen it
up. No go. When I throw a wrench on the antenna base, grip the coupler
tightly, and try to turn the antenna out, something turns, but it isn't
the
antenna coming out. I think the metal threaded socket the antenna screws
into is turning in the plastic coupler body.

Now what? How do I get the antenna loose from the threaded metal socket
without damaging the coupler? I'm worried that if I keep twisting, I
might
twist off a wire inside the coupler unit that connects the pc board to the
antenna.

How does the small pc board inside the coupler body connect to the
threaded
antenna socket?

Well, this probably won't help much, but here's something to think
about. Most coupler PCBs connect to the antenna's metal insert (at the top
end of the plastic housing) by a single pin connector. Male on the metal
insert, female on the PCB usually, although some are reversed. If the
connector pins in your coupler are round, your PCB may not be damaged. Yet.
If your pins are the flat bladed type, and the metal insert turned, well,
results may not be good to say the least.
My advice now is to stop. STOP! Once the metal insert turns, even a
little bit, the watertight seal is broken, and water WILL enter and eat the
PCB for lunch. You may be able to temporarily seal the metal insert with
some flexible sealant like clear silicon sealer, but there is a tremendous
stress at this point by the antenna itself whipped by wind and boat
lurching.
Might be good to start looking for a new coupler body (or at least a
used one that is in better shape than yours is now).
Not to brag, but I'll bet more than one of us has "been there, done
that"!
