Yes there is Kevin, it is called a relay, and it goes 'clack' in the night!
In the distant past I used relays to switch an open wire feeder between legs
of V beams at HF running 1 kW, using the 'open' type of relay used for
power switching, rated at 15 amps, inside a weatherproof container. Just
don't 'hot switch'. One other precaution, don't compare antennas too often
at 3am, you will wake the neighbours - or in your case the Mountain Lions.

Subject: [Elecraft] A/B antenna switch for ladder line fed antennas
I have a fancy switch for A/B antenna testing for coaxially fed antennas
but do not know what folks use for antenna switches with antennas fed by
ladder lines. I want to compare a 160 meter full wave loop fed with
homebrew ladder line to a G5RV fed by 450 window line. Any suggestions? I
knife switch of some sort like we used in grade school science labs in the
'60s? Or is there something more modern?
