MFJ 1703B - SWITCH, ANT/XMTR CROSS OVER SWITCH, 1.8-54MHZ Manual
MFJ-1703B Antenna/Transceiver
RF Safety Switch
The MFJ-1703B is an antenna-to-transceiver safety switch designed to help protect your radios by
ensuring both radios are always connected to an antenna. You can also connect a dummy load and
easily switch between the antenna and dummy load.
OPERATION
The MFJ-1703B uses SO-239 for radio and antenna connections. Connect one antenna or dummy load
to 1 and the other antenna or dummy load to 2. Connect one radio to A and the other radio to B.
The MFJ-1703B is an antenna-to-transceiver safety switch designed to safely connect an ANTENNA 1
to a RADIO A and at the same time connecting an ANTENNA 2 to a RADIO B.
By moving the front-panel switch to the right, the connections are reversed: ANTENNA 1 to RADIO
B, and ANTENNA 2 to RADIO A.
In either switch position, both radios are always connected to an antenna or dummy load.
WARNING:
Never transmitter while changing the switch position!
