- RoHS and REACH compliant 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 TW3320/TW3322 has a two stage Low Noise Amplifier with a mid -section SAW . An optional tight pre -filter is available with part number TW3322 to protect against saturation by high level sub-harmonics and L-Band signals. The TW332 0/3322 is housed in a permanent mount industrial-grade wea ther-proof enclosure. T wo options for pole mounting are available an L-bracket (P/N#23 -0040-0) or a pipe mount (P/N#23-0065-0) TW3320/TW3322 Shown with Low Profile Radome. Conical Radome also available
