Long Cable GSM Antenna Solution for Underground Installation
AddPac GSM Antenna Solution provides high-performance GSM gateway antenna solution for small enterprise, public offices and small & medium call termination service provider. AddPac GSM Antenna Solution consist of three (3) product line up like as AP-GSM-ANT0, AP-GSM-ANT1, and AP-GSM-ANT2.
AP-GSM-ANT0 is small & short antenna style and is directly connected on antenna interface connector of AddPac GSM gateway. AP-GSM-ANT0 has no cable and very easy to handle and manage in case of multi-port gsm gateway. This antenna is very comfortable when GSM gateway is installed in Open Space and very close to window side in office building.
AP-GSM-ANT1 gsm antenna has 2m cable length. So this antenna is comfortable when GSM gateway is Rack-Mount installed. This antenna provides reasonable performance when GSM gateway installation location is also close to window side in office building. But it is little bit difficult to handle and manage because this antenna also has 2m cable length. In case of multi-port gsm gateway, we recommend antenna combiner (4:1) gsm module should be used for easy handling.
AP-GSM-ANT2 gsm antenna has 20m cable length and big antenna height comparing with previous one. 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 increase the antenna height and cable diameter. This antenna is very useful for underground installation when gsm gateway installation location is too far to window side in office building especially. In case of multi-port gsm gateway, we recommend antenna combiner (4:1) gsm module should be used for biggest antenna easy handling.
