The PCTEL GPS-TMG-40NCS GPS timing reference antenna is specifically designed for long-lasting, trouble-free deployments in congested cell-site applications. The 40 dB high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs. The proprietary quadrifiliar helix design, coupled with multi-stage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas. It includes universal mounting hardware consisting of economy collar mount (GPS-TMG-MRNMNT).
