Left Wingtip VOR Antenna, Metal Skinned Conductive, Sportcraft AntennasThis wingtip VOR antenna is designed to fit inside larger fiberglass wing tips on metal (Conductive, that is) airplanes such as T-18's, RV's, Bonanza's, etc. The wing tips must have internal dimensions of at least 11" x 24" and generally fit better on the bottom surface. The VSWR is normally less than 2.0:1 over a freqency band of 108 to 127 MHz, but could be higher due to installation factors.
All Archer antenna designs for both metal and composite aircraft are meant for internal installation in either fiberglass wingtips or fairings of some type in conductive aircraft or inside the structures of composite aircraft. They are mainly constructed of Alclad .016" thick 2024 aluminum strips arranged in a manner that allows tuning the antennas to a level beyond that of most antennas available today.
