Well, the specs for LMR400 (same frequency - same length) is 0.388 dB
and 9913 is .421 dB. RG-6 would be 0.932 dB.
So, if 0.34 is too much, the others you mentioned would be no solution.

I was told that cable starts to act like lossy waveguide when the cable
gets large and the frequency get high. I now see that good RF cable
manufactures and sellers now publish the upper frequency limit when they
publish loss for larger cable.

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!
I
5" Air Dielectric HJ series
Loss per 100'
50 MHz = 0.0547dB
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
outer conductor distance.

Anyone know the loss of HJ9-50 at any frequency? (yea, it's BIG stuff!)
