Exactly. For example 1 5/8" hardline can't be used for 2.4GHz, but
7/8 works fine.

Thanks for the quick reply. I couldn't find that anywhere on the net.
I have a guy who is telling me that 0.34 dB (at 900 MHz)
is too much loss on a SCANNER antenna run. LOL!
I'm going to ask him if I should use HJ9-50 instead. ;->
Although I have no idea how I could connect it to the antenna!

5" Air Dielectric HJ series
Loss per 100'

150MHz = 0.0981dB
300MHz = 0.143dB
450MHz = 0.180dB
800MHz = 0.250dB
960MHz = 0.278dB
960MHz is the highest usable frequency because the inner conductor to

Has anyone implemented a simulcast (multiple TX's on the same channel) system
