Baltimore Aircol makes the best towers for GMRS repeaters, even better than Rohn.

Are you mounting this outside or inside the building?

Reason I ask is the fans in the side will let rain and moisture in.  But it would be simple enough to construct a 'hood' that would be open on the bottom and allow air flow while keeping the interior dry.  Just a thought.

This will be indoors, but it is also designed to stand on end so the fans will be out of the elements. I have also looked into building hoods for if it was laying flat.

Excellent!  Thank you for documenting it in pictures.

I am sorry to be the munny-grubber but...approximate hardware cost?  Any guesstimate on the expected range?

Spectacular!  I was too awestruck by your build (or simply too stupid) to notice that you went to the trouble of linking the components.  Very commendable!

Thank you Cactusboy19!
