Description
Moisture and temperature sensors allow the system to activate when temperatures are below 38° F and when precipitation exists. Heating elements supply heat uniformly over the surface of the defrost panel. A de-icing system prevents signal loss due to snow and ice build-up on the surface of the reflector. Larger offset dishes and Vertex series antennas.
