ANTENNA COAXSIAL SWITCH
4
POSITIONS, 2 KW PEP
The MS-S4A consists of two units, the weatherproof switching box that mounts on your tower or mast and the
web or manual
control unit thats placed at your operating station.
Connected to internet switch or PC via Wi-Fi. Also there is option to select the antenna manually.
The MS-S4A provides ease in switching antennas without disconnecting a connector. This 4
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 2x16A)
T
he 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 nterference.
