Okay, now it's my time to change the subject, if slightly :-)

I need to decouple my inverted-L from the nearby RX antennas (EWEs and
  pennants in my 44x140 city lot).

In is books, ON4UN suggests using a normally-open SPDT relay to achieve
this, tying it to the (Orion's) <200ma/12v PTT OUT to energize the relay.
When closed, the relay will have to handle a KW.  My idea is to put the
relay in an electrical box as K2ZJ did with his beverage box. While 'd
love to power it through a Bias-Tee, for the time being I'll run a
separate power cable to the box.

QUESTION: What sort of relay to scrounge/purchase? There's a hamfest
happening this weekend I may be able to attend, so any quick, *specific*
response is appreciated.

Thanks,
