Re: LMR-400 Variants?



Charles,
Works fine on 9913, but if you go through the copper plating on the LMR400
you cannot get a reliable connection to the center conductor.

R.F. Parts ( www.rfparts.com ) has the right connectors, unless you have
some old stock you want to use. Also LMR400 will work well to several GHz,
but you must use the Teflon type not the delrin type for anything above 1.3
GHz.
