Overview
The PCTEL GNSS1-TMG-26N global GNSS timing reference antenna is specifically designed for long-lasting, trouble-free deployment 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 multi-stage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas. This multi-band antenna covers GPS L1, Galileo E1, GLONASS L1 as well as BeiDou B1 frequencies.
The unique radome shape of the GNSS1-TMG-26N antenna sheds water and ice, while eliminating problems associated with bird perching. The antenna features transient voltage suppression as well as protection from reverse polarity and electrostatic discharge (ESD).
PCTEL offers an array of compatible mounting configurations. Custom models or site kits options are also available.
