Bill:

Some many years ago I needed such a switch for some experiments on 2 meters. Since it was the weekend and I was in a
hurry, I took one of the old A. H. & H. DPDT toggle switches, some bus wire and 4 N connectors and made one with leads
as short as I could make them. It is still in use, and makes a surprisingly small impedance bump in the line. I
suspect at HF, it would be invisible.

Does anyone know of a source for a switch which accepts two incoming
PL-259's (A/B) and spits out either A/B or B/A, depending on switch setting.
The object is to switch the feedpoints of a rhombic antenna from one end to
the other. The two "incoming" lines to the switch are from either end of
the rhombic. The two outgoing (from the switch) go to a dummy load and the
tuner/transceiver.

TIA.
