1.2 GPS Antenna
In base stations where a GPS antenna does not exist or is not available, a new GPS antenna
must be installed. The WLS can provide up to 38 mA of +5 vDC power to the antenna port for
powering an active antenna.
If the site has an existing GPS antenna (e.g. CDMA site) a GPS splitter is installed. The splitter
passes DC from the base station GPS receiver to the base station GPS antenna as normal. DC
is blocked from the WLS at the splitter.
