[Microwave] Cable specs wanted

[Dr. Gerald N. Johnson]

I only found one Andrew catalog in my library, number 35 dated from 
1991. For FSJ1/50A it says good to 20.4 GHz and loss at 10 GHz is 21.8 
dB / 100 feet.

LMR240 is a similar size and a length I had measured at MUD 2014 had 
half the dB loss per 100 feet as good UT-141 at 10 GHz, though the 
catalog data stops at 6 GHz. The measurement was 1.75 dB loss for 5'10" 
that would be 30 dB /100 feet. Extrapolating the LMR plotted data shows 
27.5 dB / 100 feet at 10 GHz.
