[Elecraft] A/B antenna switch for ladder line fed antennas

[David Toepfer]

I have thought of pairing up a 4-position Alpha-Delta coax switch back-to-back,
but time and expense have prevented it.  I have also thought through a few
schematics to do it remotely to my attic with relays.  But here's a simple
homebrew one (<http://www.io.com/~n5fc/ant_sw.htm>) I found at N5ESE's site
(<http://www.io.com/~n5fc/>).  There's some good info here.
