Looking for the attenuation figures for Andrew FSJ1/50- this is the older 
cable type, NOT the current type FSJ1/50A. I suspect they are similar but 
would like to have this confirmed.  Particularly interested in attenuation 
figures for 10 GHz. I can't find any references to cable loss figures in the 
microwave region for this older cable type anywhere on the internet. (so 
far!)

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.

Tks Jerry- yes-I have that data on the FSJ1/50A. Getting data on the older 
cable type is what I want as I have a quantity of it here.  Forgot I had it 
actually! Just came across a box of it when sorting out some other cables a 
few days back. I suspect it will be similar - as regards loss at 10 GHz-  to 
the A suffix current cable, but really want to get that confirmed- else I'll 
have to connectorise a few meters of it and make some measurements.

I found an older catalog on line, but catalog 26 didn't admit FSJ1-50, 
so its not a benefit. I did find a few references to FSJ1-50 using 
google but nothing to answer your questions.
