High Power, Four-Square, 4 direction Transmit system.

Four-Square, 4 direction Transmit system, 7 kW CW ICAS, 120W dummy load included.

LowBandSytem`s 4SQUARE/TX Switch Relay Units use classic monoband Hybrid design.

Power, Watts, ICAS: 7000W at 1,5 : 1 SWR, ICAS

Robust, Inert gas filled high current relays from Soviet Army (REN-33, 27VDC coils) and К15У-1capasitors.

SO-239 input and output connector with PTFE Dielectric and Silver Plating.

N connectors on demand.

DIN 7/16 input connector on demand.

RF volatge detector to control DUMPED power on a system`s load resistor.

4 wires control line.

Phoenix plugable connector.

IP65 steel enclosure.

Includes very robust 50 ohm, 120Watts very conservative rating, non-inductive dummy load of two big ceramic resistors. 

Switch relay units are made to any band of your choise, 160-10 meters.

80 meters system requiers also CW stub remote relay switches at the base of each vertical.

These switch relay unit requires:
