[Amps] High SWR

[Carl]

I use the Belden catalog as the reference. A true RG cable has an 
established set of specs that doesnt vary on a whim.

What causes confusion is the RG clone variants and non RG designations. 
I dont know if its improved but Radio Shack coax of the past was a prime 
example of a mighty inferior product.

Ive run RG-6 fed inverted vees or slopers on 160/80 as well as 450' of 
CATV hardline with RG-11 foam jumpers into 4 or 5:1 VSWR's at times with 
no ill effects at 1200-1300W. Ferrite sleeve baluns at both ends 
eliminated any hot outer shields. Over 300 countries on both bands as 
well as big contest scores attests to my lack of concern when it doesnt 
amount to the proverbial hill or beans.

OTOH, I fight for tenths of a dB on VHF and above!

REPLY:

2004 ARRL Handbook on CD, table 19.1. As I said in another post, I was
mistaken about RG-213, but the other RG-8 style coax versions are
almost all rated at 600 VRMS. RG-213 is an exception. Sorry for the
goof.
