[TowerTalk] Heliax question

[Stan Stockton]

Thanks, Mike.

It is corrugated outer conductor like normal Heliax.  I haven’t measured the inner conductor yet but did attempt to drill a straight 1/4” hole so I could try to screw in the center pin used on the tubular center conductor on 7/8”.  There was plenty of wall thickness left.  I’m just guessing the inner conductor is about 3/8”. Solid foam dielectric.  I can get a 7/8” connector over this stuff though it measures larger in diameter.  I  think if I had center pins that were made for 7/8” solid inner conductor Heliax, I might be in business.

One is the diameter of the center conductor. The other is a description of the dielectric material. Is it a solid foam, or is it mostly air with a helical dielectric spacer?
