Install GPS Antennas
As mentioned earlier, there are two models of GPS antennas that can be used with the Ripwave
Base Station, as shown in Figures 21 and 22: Motorola Timing 2000 and VIC 100. The system
will use either one or two GPS antenna modules.

The mounting location for the GPS antenna is determined during the site survey. When
installing, ensure that the following requirements are met:
• The GPS antenna is installed within 100 feet of the BTS.
• The GPS antenna is located to provide the widest view of the sky (objects such as
buildings or trees can interfere with signals from the satellite).
