Bob,
Suggestion:
Roller paint extension (6m) works very well for booms and many other antenna application and relatively cheap. In case more strength required one may use the different size (as telescopic) with some epoxy glue to make the boom more stiffer. I used same a lot for also collinear verticals, Yagi boom etc..
For the elevation motor boom I use aluminum tube over the fiberglass tube secured with epoxy glue, so that the clamp does not crush the fiberglass boom..

Hi Bob,
I had to use two shorter fibreglass poles so I found a short length of ali pole which was a tight fit INSIDE the fibreglass one. This supports the glass material where it is being clamped.
To further protect the fibreglass on the outside I slipped some slit pieces of pvc downpipe underneath the clamps before tightening it.
I am not sure if it is the best answer but it has survived > ten years here.
Good luck

How do others attach their fiberglass boom to the elevation rotor on a G-5500? Just use the boom clamps provided? Make a sleeve to fit between the smaller fiberglass boom and elevation rotor inside diameter? Drill a hole and pin it?
All ideas appreciated.
