Default Unknown coax id help?

If you muliply that loss out, it's about 17 dB loss per 100 feet. That
would be considered pretty lossy...but...since you're only using 5 feet,
it's probably not going to be a deal breaker Andrew 1/2" hardline is
about 3.6 dB per 100 feet (granted it is NOT RG-58 sized!)...

The label on this coax reads:

"CFD200-NL LOW LOSS 50 OHM COAXIAL CABLE COMMATE/PEWC 3D"

All I could find was a spec saying it has a VF of .83 and I measured
the OD (0.195"). The cable is very stiff for it's size - like 9913
almost.

Anyone care to guess? I'd love to take it apart (it's a RP-TNC - N
Male 5' pigtail) but it's such a nice job I don't want to. Maybe it's
a copy of LMR-200?




I guess my Google skills are better than yours! :^)

Try: http://www.commate.com.tw/

Click on "Low Loss Cables,

then click on "CFD200"

Looks pretty Lossy, to me, if you are going to use it at 2.6GHz.

Actually, I did google and yahoo and I saw the reference to the tw
website but I passed, fearing language problems. Guess I should
have given it a look see.

Lossy? My math says 0.845 db loss for my 5' pigtail - from what
I've read recently that's not to bad for a rg-58 size pigtail, esp. on
2.4 gigs...

Maybe I'm wrong? Feel free to teach me. :-)

Thanks for the link.
