Rock Base Pole Mount Suggestions

Any suggestions on a pole for the actual receiver? There seems to be a black hole of information/suggestions around what to use and what others are using. Thanks!

Different mounts for different situations.

I designed and printed a part that slips into the end of a piece of Unistrut, and holds the 5/8"-11 bolt that the antenna mounts to.

It’s the green piece barely visible in this photo, between the antenna and Unistrut.
