Long Cable GPS Antenna Solution for Underground Installation

AddPac active GPS antenna solution for embedded GPS NTP server provides high-performance GPS antenna solution for various enterprise applications. AddPac long cable active GPS antenna solution consist of three(3) product line up like as AP-GPS-ANT2, AP-GPS-ANT3 and AP-GPS-ANT(4).

AP-GPS-ANT2 GPS antenna has 30m cable length. This antenna is special ordering item and expensive. Normally long distance cable antenna length means antenna performance degradation due to resistance characteristic. To compensate performance degradation due to cable length, we use high quality antenna cable and increase cable diameter to reduce cable resistance characteristic. This antenna is very useful for underground installation when GPS NTP server installation location is too far to window side in office building especially.

For special ordering GPS antenna, AP-GPS-ANT3 GPS antenna has 40m cable length and AP-GPS-ANT4 GPS antenna has 50m cable length. These long-distance GSP antennas provide reasonable GPS signal quality.
