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.

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.
