Hi Gary;
Just a small correction - the Alfa Spid is actually made in Poland but with
much input from us in Canada (Alfa Radio). For mounting outside of a tower
like you describe, it's something the RAK can handle easily. They have two
significant bearings and can take a lot of side loading before we'd call it
"abuse".
You'd know which one I'd suggest..... but there might be bias involved!
