Where's a good web/mail-order source for replacement telescoping
antennas? MCM used to have a very wide selection, and Radio Shack
stores had a narrower but not so bad selection, and between those two I
could usually find near-exact replacements, but they seem to have
greatly cut back in the past couple of years. (Either that or I am
completely unable to find their old selections via their
hard-to-navigate web pages.)
