MS-S3 REMOTE ANTENNA COAXSIAL SWITCH , 3 POSITIONS, 2 KW PEP

The MS-S3 consists of two units, the weatherproof switching box that mounts on your tower or mast and the control unit thats placed at

your operating station.

The MS-S3 provides ease in switching antennas without disconnecting a connector. This 3-position

antenna switch can be used for 46 to 75 ohm systems, plus handle 2000 watts SSB, 1500 watts CW.

(Tested for extended periods with ACOM1500-power amplifier)

All unused terminals are automatically grounded for static/lightning/RF protection.

High power provide special relays with powerful changeover contacts (max current 2x16 A the breakdown

voltage between contact 1 kV)

When power off all antenna outputs are also grounded.

Cast aluminum housing ensures a high degree of shielding and protection from interference.

For independent control switching antennas is use remotes manual control .
