[amsat-bb] Re: Fibreglass tube for G5500?

[Chris Bloy]

Hi all,

Thank you all very much for your input and as expected the aluminium pole isn't an option, so I am going down the route of fibreglass tube with wood insert.

Just need to source a UK company that can supply the tubing! I have contacted Engineering Composites and will await a price!

All the best!
