MFJ-4726RC 6–Position Antenna/Transceiver Switch Remote Control
INTRODUCTION
Thank you for purchasing the MFJ-4726RC 6-Position Antenna/Transceiver Switch Remote Control. This
Remote Control allows the user to remotely operate the MFJ-4726 Desktop/Remote Antenna/Transceiver Switch, which is a versatile multiple Antenna/Transceiver Switch designed to switch up to six 50-ohm antenna systems or six transceivers in any combination. It handles high power, up to 1500 Watts and sealed relays offer excellent life and connection reliability. The unit is operational from 1-60 MHz and useable to 150 MHz.
The MFJ-4726RC 6-Position Antenna/Transceiver Switch Remote Control uses two simple rotary switches to select one-of-six antennas or six transceivers in any combination. Place the MFJ-4726 Desktop/Remote Antenna/Transceiver Switch out-of-way under your desk or in another room and use a remote control. In the OFF/Remote position, all inputs are grounded or control is transferred to the MFJ-4726RC Remote Control. All unused inputs are grounded. You can connect a sense line to your transceiver so when it’s off all inputs are automatically grounded.
