Re: LMR-400 vs 9913F?



Allen,
LMR 400 and 9913 F both have a foam core. This prevents drawing in moisture 
and condensing it into water like the old 9913 with an "air dielectric" 
breathing space. Times wire and cable makes an ultra flex LMR 400 slightly 
greater loss, stranded center conductor. The PL259 connectors will solder 
directly on to LMR 400 or 9913, special connectors are needed for N, TNC, 
and BNC types. Suggest R.F. Parts (rfparts.com) for connectors. The big 
benifit to LMR 400 is weight, and cost. LMR 600 and larger requires special 
connectors that are not low cost.
