TW3440/TW3442 高增益、严格任务、长电缆天线

The TW3440/TW3442 employ Tallysman’s unique Accutenna® technology covering the GPS L1, GLONASS G1, and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It provides truly circular response over its entire bandwidth thereby producing superior multipath signal rejection resulting in higher accuracy of position and timing.TW3440/TW3442 timing antennaTW3440/TW3442 timing antenna

Specifications

The TW3442 has an additional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW3440/TW3442 are housed in a through-hole mount, weather-proof enclosure for permanent installations. They are available with either a flat or conical radome in either grey or white. The TW3440/TW3442 is also available with either a TNC or N-Type connector on the base of the antenna or with a flying lead and a variety of connectors.

An L-Bracket or Pipe Mount (part numbers 23-0040-0, 23-0065-0 respectively) are available for non-rooftop installation. They are IP67, RoHS, and REACH compliant.
