Actually, according to <http://www.timesmicrowave.com/cgi-bin/calculate.pl>, RG-400 has slightly higher loss than RG-223. I would've guessed otherwise, but there it is in B/W. Given that, I'd prefer RG-223 over the teflon insulated coax due to its better flexibility. RG-400 does have substantially higher power handling capability, slightly higher loss notwithstanding. Probably due to either higher dielectric breakdown voltage or higher max. operating temperature. So if you're feeding a very high power out of an amp, you'll need RG-400. Bob NO6B
