[TowerTalk] Securing vertical to concrete post?

[john at kk9a.com]

Jim has a great idea but it may be more heavy duty than K9GS needs.  
Searching using his suggested terms show a lot of pole brackets but most 
used worm gear hose clamps and are for signs or cameras. I just thought 
of a place that I worked at in Illinois decades ago that made large 
mounting brackets.

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:
