Alright DIY nigs,
I'm looking to build a helical for INMARSAT reception ~1.5GHz. I've got an antenna calculator and a book on antennas, for the specs but I need a form to wrap the coil around.

Any ideas?

The form needs to be around 2.5" in diameter, rigid, non-conductive, and allow for fabricating a matching network between the coil and the ground plane. Should keep the correct coil spacing aswell.

I would like something easy instead of making a rigid pole and drilling a bunch of shit and adding support element like in pic related.
