Minimize Snow and Weather Effects-VORTAC Task II TACAN Antenna.

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. The polyurethane shroud showed the most promise of all the techniques tested. (Author)
