[TowerTalk] New? Cable

[Richard Karlquist]

I vaguely remember someone posting to TT
that LMR-400 is less than 50 cents a foot
in quantity.  At 46 cents, I don't see
how this knockoff is any bargain.  

The toughest spec to copy wrt LMR-400
IMHO is velocity factor (=85%).  See
if they guarantee that, and if they
do, get a sample and test it.  I've
been burned on this before.  Note that
even if you don't care about VF per se, if it
is below the design value, the Zo will be
off and loss will go up.  BTW, is the
center conductor the same size as LMR-400?
Sometimes a smaller center conductor is
used to compensate for low VF.
