INVOLUTE AUTOMATION

GROUND AND SHIPBORNE SUB SYSTEM EL/AZ LM-122

Antennae positioners are for precise positioning and tracking applications chiefly used in communication industry. Different models are available with Azimuth / Elevation options. Dual torque drives are also offered for controlling larger antennae. Customized user interface can be offered on PC for operation and feedback. Positioners with (MIL grade) environmental and EMC/EMI compatible specifications are offered at additional cost.
