The TW3320/TW3322 is a high performance antenna covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band (1575 to 1606 MHz). It features a patch element with 40% wider bandwidth than hitherto available in this format. Unlike its competitors, both GPS-L1 and GLONASS signals are included in the 1dB received power bandwidth.

The TW3322 has an additional tight pre- filter to protect against saturation by high level sub-harmonics and L-Band signals. 预滤波
The TW3320/TW3322 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 TW3320/TW3322 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. TNC、N-Type连接器等可选。
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. 非屋顶有L型支架、管型支架可选。
