Re: Which is the best material for an aerial sleeve?
I seem to recall that polystyrene has some nice dielectric properties (see the HRO HF coil-packs), but is not the toughest material in the world. I used to work for a company where one of the senior technical guys had a big thing about using PEEK (polyether ether ketone) for all things RF. This got a big thumbs up from the guy who had to machine it, who said it was a dream to work with.
