MFJ 1704 Antenna Switches

Mount one of these MFJ 1704 Antenna Switches and you will have more than the convenience of instantly selecting any of four antennas or center ground positions. They come complete with replaceable lightning surge protection that helps to protect against distant lightning-induced surges and static.

When these antenna switches are in the center position, all connectors are disconnected and grounded. If the switch is turned to an active connector, the other connectors are automatically grounded. The active connector is automatically protected with the replaceable lightning/surge protector.

MFJ 1704 antenna switches utilize heavy cast metal construction and ball bearings for smooth switching.
