  • General
    4.5M remote sensing satellite deployable trailer mount antenna is mainly used in Marine, meteorology, remote sensing satellite. 4.5M remote sensing satellite deployable trailer mount antenna adopt ring-focus dual shaped reflector, AZ-EL + three axis type deployable trailer mount antenna, at the same time inclined shaft is designed as the upsidedown mechanism, antenna mount is the trailer car.
    4.5M remote sensing satellite deployable trailer mount antenna can operate in L, S or X single band, or operate in L/S, L/X or S/X dual frequency band, and it can also operate in L/S/KU, L/X/KU or S/X/KU tri-band, Ku-band can be applied for Satellite communication. When 4.5M remote sensing satellite deployable trailer mount antenna three frequency bands work at the same time, it adopts three-frequency compound feed source, feedback type operation. Tracking mode includes manual tracking, programme tracking and single pulse tracking program. System include antenna reflector, antenna pedestal, feed system, servo tracking system, upsidedown mechanism, corollary equipment include the antenna trailer, Tow Tractor, Calibration signal source, beacon horn, elevator mechanism, north seeker and protection rod.
