see the data out there for tuning those 4 cables, 75 ohm nominal coax, with
a fairly high VP in order to make the required length and tuning involved. We
have that coax cable available
I recently bought a spool of Steve's 75 ohm RG-11 foam to feed my high
dipoles. I also measured it with VNWA and dumped the data into AC6LA's
ZPlots to get the fundamental transmission line properties for it. It's
very nice stuff. Vf is 0.84 at VHF, attenuation data is within
measurement accuracy of Belden's published data for 8213.
