Asking anything on AMSAT-BB is ... well, you'll see ...
You will always be 90 deg off on one band. This is even an issue on
some of the LEOs where you need to flip the antenna 90 deg to maximize
gain between transmit and receive. I think with a little
weatherproofing and maybe some loctite, they'd probably be OK but they
are NOT designed for that service, so who knows. Mine has the
diiplexer in the handle and that surely would need to be potted or
something. Two feedlines would probably be better.
They have a clamp mount that lets you clamp the boom to a variety of
shapes and it would probably fit around a mast ... but it's not
designed to be permanent.
They do work great for portable satellite work.
