Operating across 1.2-1.6 GHz, the AW-GP1227-35 gnss / gps antenna provides 35 dBi gain and rhcp polarization. The design targets gnss survey / rtk deployments that demand reliable coverage and stable impedance matching.
Radiation Pattern and Gain
As an omnidirectional radiator, it provides a full 360 degree azimuth pattern with an approximate 90 degree elevation beamwidth, distributing energy evenly around the mast. The rated gain of 35 dBi is referenced to an isotropic radiator.
Mechanical and Electrical Specifications
Mechanically, the AW-GP1227-35 measures 152 x 152 x 62 mm and is housed in a Survey-grade radome. The standard interface is a TNC-Female connector, with a nominal impedance of 50 ohms and a typical VSWR of 1.5:1 or better. The element withstands up to 5 W of input power.
Installation Guidance
The recommended installation is outdoor, pole-mounted. The enclosure carries an IP67 environmental rating for outdoor exposure. For best results, mount the antenna with clear line of sight to the served area and bond all outdoor hardware to a proper grounding system.
