Good info, Bob -- Pasternack has the RG-400 for only a little more than the
RG-142B/U, but you have to persuade them to honor their special sale terms
of a $25 minimum purchase and free shipping -- good through 7/31. Someone
else reported being told on the phone that their minimum is $100, so you
may have to insist.
