I do not want to drill into the concrete out of concern for letting in moisture/saltwater. Any ideas?73,Gary K9GS

What you want is apparently called a "pole strap mount" or "pole band mount"

They're available in a variety of sizes and strengths and are used for 
things like mounting signs and electrical equipment (and, now, 5G cell 
stations) on power poles, light poles, and the like.  If it can hold up 
a 15 kVA transformer, I think it can hold up your antenna.

Materials include aluminum, galvanized and stainless steel.

Here's an example:
