PCTEL's GNSS1-TMG-26NMS global GNSS timing reference antennas are specifically designed for long-lasting, trouble-free deployments in congested cell-site applications. The low noise, high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs. The proprietary quadrifiliar helix design, coupled with multistage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas. This multiband antenna covers GPS L1, GALILEO E1, GLONASS L1 as well as BEIDOU B1 (COMPASS) frequencies. Their unique radome shape sheds water and ice, while eliminating problems associated with bird perching. Pctel offers an array of compatible mounting configurations. custom models or site kits options are also available.
