[amsat-bb] Yaeus G-5500 rotator boom mounting

[Jean Marc Momple]

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..
