mfj desktop or remote antenna switches desk/remote 6/4 pos antenna switches antenna switch on your desk or place it out-of-way under your desk or in another room and use a remote control a simple rotary switch lets you select 1 of 6 antennas all unused inputs are back of unit grounded you can connect a sense line to your transceiver so when it s off all inputs are automatically grounded in the off position all inputs are grounded or control is transferred to the mfj-4716rc $39.95 remote control ultra-fast gas discharge tube lightning surge protector protects transceiver and safely shunts static electricity and lightning induced surges safely to ground does not protect against a direct lightning hit super easy-to-use just one simple rotary switch there are no complicated computer
