Satellite Antenna De-icing Systems for Prodelin Antennas
DESCRIPTION
The SATCOM De-icing system consists of a factory pre-wired control unit, heater pads for reflector coverage, and a feedhorn
heater. All systems are engineered to be easily assembled, installed and operated.
The control unit has three modes of operation: Automatic, Manual Off and Manual On. The Automatic mode allows the control to
monitor the ambient temperature and sense the presence of moisture. An ambient temperature of less than 40 degrees F and the
presence of moisture activate a heater contactor. The heater contactor is rated up to 50 amps. The heaters will remain on for a factory
preset time of one hour longer than conditions warrant. The Manual Off mode turns the heaters off, regardless of the weather
conditions. The Manual On mode turns the heaters on, regardless of the weather conditions. Control units are factory preset to operate
on 120 to 240 volts, single or three phase power. All cabling to attach the heater pads is factory pre-wired. The larger systems have a
control unit with remote moisture sensor.
The heater pads consist of heater wire sandwiched between layers of aluminum foil. Heater pads allow for a faster install without the
need for templates. The aluminum foil is coated with an aggressive acrylic adhesive and a peel and stick liner. Watt density of the
heater pads, depending on the reflector, is between 40 and 55 watts per square foot. The aggressive acrylic adhesive adheres to a
variety of substrates and will not release when pad temperature increases. Heater pads have water resistant connectors that plug into
the cables from the control unit.
The feedhorn heaters consist of heater wire attached to a strap and covered with heatshrink. They are attached to a rib on the feedhorn.
Installation of the de-ice system consists of applying the heater pads to the backside of the reflector, mounting the control unit / moisture
sensor, routing power to the control unit, attaching the feedhorn heater, and connecting the heater pads to the control cables.
The De-icing systems can be custom made for a variety of antennas and applications.

- Page 3 Control and Harness APPLY THE HEATER PADS TO THE REFLECTOR PANELS 1. Properly support the reflector panel so that no distortion results from heater pad attachment. Verify differences in reflector panels have been accounted for. 2. The surface temperature of the panel should be above 50 degrees Fahrenheit, 10 degrees Celsius for proper adhesion of the heater pads.
- Page 4 Heater Pad Placement and Lead Connections CONNECT THE HEATER PAD LEADS 1. Plug the heater pad connectors together as illustrated on the Heater Pad Placement and Lead Connections Drawing. The connectors are difficult to fully seat, and will not properly seal until a small snap is felt. Drill 7/16” holes through ribs and insert grommets if extra lead support is desired.
- Page 5 2. Attach a sensor mounting bracket to the feedarm at the desired location. Self tapping screws or a u-bolt may be used for attachment. The down leg of the bracket should be adjusted so that it points downward. See the Sensor Attachment Drawing. 3.
- Page 6 ATTACH THE FEEDHORN HEATERS TO THE FEEDHORNS 1. Each conductor coming from the Feedhorn Heater Cable connects to a splitter that branches into two female leads. One female lead from each splitter should plug into each feedhorn heater. 2. Route the feedhorn heater cable along the feedhorn support arm. 3.
- Page 7 TEST THE HEATER SYSTEM 1. Apply 240 VAC single phase power to the system. 2. Allow the sensor to go through its start-up test. 3. When the sensor enters the Automatic Enabled mode (steady green indicator), push the selector switch twice to place the sensor in the Manual On mode (steady amber indicator).
