BlankI have some 1-5/8" Air Dielectric Andrew Heliax Coaxial Cable, HJ7-50A, 
RG819A/U that I will entertain offers on and may or maynot be willing to sell. 
PER ANDREW Catalog  WHEN NEWHJ7-50A has an average power rating of 
approximately 110kW at 2.0 MHz with attenuation of of 0.0280 dB/100 feet.  At 
10 MHz 48 kW average power rating and a attenuation of 0.0640 dB/100 feet.  The 
published rating at 30 MHz is 27kW average and a attenuation of 0.112 dB/100 
feet.

For VHF and UHF the Andrew Catalog shows a rating of 11.7 kW average power and 
a attenuation of 0.252 dB/100 feet at 150 MHz.  At 450 MHz the published 
average power is 6.57 kW and a attenuation of 0.478 dB/100 feet

This coaxial cable would work in HF, VHF, UHF and even higher but does require 
pressurization due to the air dielectric.
