[SCCC] Fw: TWB-4001

[Tom Rauch]

I finally got around to measuring the TWB 4001 LMR400 cable 
from eBay seller emcommunications. I measured the following 
based on a 1000 foot long sample. NOTE: I did not measure 
the sample to be sure it was 1000 feet, I just measured the 
whole roll as it arrived.

MHz and LOSS per 100 feet. The manufacturer's spec is in ( ) 
:

1=  .178dB.
2=    .261
4 = .438
7= .530
15= .685
30= .854  (.7)
50=  1.07 (.9)
100= 1.40
144= 1.64
150=  1.67 (1.5)
200= 1.91
450= 2.93 (2.7)
500= 3.10

Please note I used only PL-259's. Loss above 100 MHz might 
be modified a tiny bit by the connector bump, increasing as 
frequency increases. It would not affect anything below 100 
MHz.

Connectors fit the cable well.

These measurements are right in line with the specs. There 
is always some variation between samples and the cable was 
pretty hot when I tested it. The temp here was 105 F today 
and the cable had been sitting outside for a while.

So it looks like good cable.
