I get the general idea of what type of relay to look for but where do you
get these???

And if I use banana plugs/binding posts at my entry points do I have to
install them in insulating material?? Something about running ladder line
through binding posts installed in a metal cabinet doesn't sound right....

Mouser, perhaps...

The banana plug receptacles typically have a plastic collar to keep
them from touching the cabinet. If you'd rather go with ceramic
feedthrough insulators, they have them in all sizes at Surplus Sales
of Nebraska. Pricey, but they got 'em.

Yes, I wasn't suggesting to shorten the banana posts to the metal, thus
shortening the two antenna leads as well.

I was more thinking about the suggestion of keeping ladder line away from
objects, not nailing it directly to the siding of your house for example.

That suggests that this unshieleded line might be influenced by objects
close by. And along those thoughts I was wondering if bringing both lines
within fractions of an inch to a common ground, the metal box, might be a
good idea.

Try http://www.action-electronics.com/nterelay.htm

they have a great index system. I would try something like the
R04-11D30-12 or something similar.
