Use this MFJ-4714 Four-position 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 4 antennas. All unused inputs are 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-4714RC, 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 buttons to learn or microprocessors to fail or generate RFI that could mask rare DX.
