A simple rotary switch lets you select 1 of 4 antennas. All unused inputs are grounded. You can connect a sense line to your transceiver so that when off, all inputs are automatically grounded. In the OFF position, all inputs are grounded or control is transferred to the MFJ-4714RC Remote Control.
Ultra-fast gas discharge tube lightning surge protector protects transceiver and safely shunts static electricity and lightning-induced surges safely to the ground. Does not protect against a direct lightning hit.
Easy to use – just one simple rotary switch. There are no complicated computer buttons to learn or microprocessors to fail or generate RFI that could mask rare DX. Use 12 VDC or 110 VDC with MFJ-1312D. For indoor use, not weather protected.
