Features

    BT-290 antenna employs quadrifilar helical structure to receive signals of GPS L1/L2, GLONASS G1/G2 and BDS B1/B2/B3 GALILEO E1/E5b bands , which features high zenithal gain, favorable low elevation gain, wide-angle circular polarization and stable phase center. The antenna is suitable for Three-system high-precision survey and military positioning and widely used in situations such as unmanned aerial vehicles, geodetic survey, road construction, marine survey, wharf container operation, maneuvers and frontier guard.

- The antenna part adopts a multi-feed point design scheme to ensure the coincidence of the phase center and the geometric center, and the influence of the antenna on the measurement error is reduced.
- Wide beam of radiation pattern can make sure good reception of signals at low elevation and normal operation in some situations of serious shielding.
- The radome can resist high and low temperature impact, water, and ultraviolet rays, which can protect the antenna to work outdoors all the year round.
