All system units (Antenna tuning and Transformer matching are inherent in the ATU and mounted inside an IP66 weatherproofed and ruggedized cabinet.

ATU shall be installation at the Antenna.

Transmitter tuning to match the antenna impedance is a manual procedure.

An Auto Tune function is offered as an option.  Input impedance is 50 ohm.

A heater element is installed inside the cabinet to reduce humidity at low temperature.

The heater element should be powered from 24 VDC via the Transmitter Cabinet.
