5 wires control line.

Phoenix plugable connector.

IP65 steel enclosure.

Includes very robust 50 ohm, 360Watts 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.

These switch relay unit requires:

One of the LowBandSytems 4 SQUARE ARRAY controllers:
