[TowerTalk] Heliax question

[Stan Stockton]

Thanks for the information, Peter. I appreciate you trying to figure it out.

LDF4.5-50 has a diameter over dielectric of .71 inches and the inner conductor is .28 inches. I don’t have anything that small.  I am positive the other coax I have is 7/8” Andrew Heliax.  This one I haven’t been able to identify is (as closely as I can measure with a tape measure) 1/8” larger over the dielectric than the 7/8”.  Just looking at the ends of them side by side one is visibly larger.

Right now I would be happy to find a part number for 7/8” Heliax with a solid center conductor or connector for same to see if I could make it work.
