Abstract:

The report covers the use of various techniques to minimize the effects of snow and ice on the RTA-2 TACAN antenna. The techniques were 1 a wire-wrapped randome with current flowing through the wires attached to the external surface of the radome 2 enlarged radomes 3 coating existing radome with hydrophobic materials and 4 providing a polyurethane shroud over the existing radome with movement of the shroud provided by antenna vibration, wind, or air inflation.
