I should have mentioned that RG-223 has a solid silver-coated copper center conductor, while RG-400 has a stranded silver-coated center conductor, which makes RG-400 better suited where flexibility counts. RG-142 has a solid steel center conductor that is solver coated and copper clad, but it should not be used where it will be flexed after installation. The big disadvantage of RG-223 is the power-handling capability. RG-223 is rated for just 86 watts at 400 MHz, while RG-400 (and RG-142) are rated for 1100 watts at 400 MHz. RG-223 has 50% greater attenuation at 50 MHz and 15% greater attenuation at 400 MHz. RG-223 will be okay in most applications, but the power-handling limitations and its attenuation should be considered.

However, RG-223 is also silver, double shielded,very flexible, and also about RG-58 size. Any reason why RG-223 would not work just as well; other than it is not a teflon cable? Sid.
