MB0414A Rooftop Antenna
This antenna has been replace by the small G3 window antenna.
The Rooftop Antenna contains a GPS receiver. It should be mounted where it has an unobstructed view of the sky. However, it can also be mounted on the side of a building, or even placed inside next to a window if required. The antenna contains a heating element which turns on automatically in very cold weather. The heater prevents ice from forming on the antenna and attenuating the GPS satellite signals. The Antenna is connected to the Coupler using 8-conductor LAN cable.
