AD-79/18D: GPS active receiving antenna

The antenna AD-79/18D is a mobile GPS active receiving antenna intended for use with mobile and portable GPS receivers. The active parts with the ceramic patch antenna are enclosed in the ABS radome. Stainless steel mounting adapter has M10 thread with washers and nut for easy mounting. The antenna could be used as standalone or in combination with our standard VHF/UHF broadband mobile antennas type AD-18/D, AD-27 or AD-18/E. With these antennas the AD-79/18D could be placed on the existing antenna base instead of one M10 mounting screw - no need to drill additional mounting hole.
The antenna has up to 5 m of RG-316 coaxial cable with SMA  female connector. Other connector types and coaxial cable lengths are available on request.
