Thanks to everyone who responded to my inquiry about freeing seized antenna
parts. I received many good ideas and in response to someone who asked that
I post a summary, here it is:
Put stainless steel hose clamps on both pieces as a place to fasten your
pipe wrenches--they grip better than plain
I replied off list as per his request but as others are replying on
list I think I should get this out to the entire group. Lye
dissolves the aluminum. Ammonia is supposed to dissolve the oxide.

What is Break Free? Where do you get it? Does it always work, on only
sometimes?

Hi Chuck,
I usually have good results with Break Free and a mallet. I usually let the
solution soak for a bit then tap around until the tubes dislodge. YMMV
depending on how bad things have oxidized. I usually also put some
anti-seize around joints when putting things back.

On Tue,
The lye definitely does eat away the pure aluminum, as I learned in my
miss spent youth! The fireballs were impressive, also, and we were
darn lucky. I think you would need to eat through the good metal just
to get to the oxide, which is on the inside. Heat would probably be
the best bet
One possible solution would be to soak the "stuck" joints a solution of sodium
hydroxide (lye, as in drain cleaner). There's a web site that discusses the
chemical reaction and the ability of lye to dissolve existing layers of
aluminum oxide. See:

Does anyone have experience freeing antenna parts that have seized with

be cutting it.
