The TW3440 | TW3442 are professional grade 40dB fixed mount Timing antennas covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). They are especially designed for mobile, precision and military applications and offer excellent circular polarized signal reception, multipath rejection and out of band signal rejection.

The TW3440/TW3442 feature a highly circular dual-feed wideband patch element, with a three stage Low Noise Amplifier. This configuration provides excellent axial ratio that is constant across the full frequency band. An optional tight pre-filter is available with part number TW3442 to protect against saturation by high level sub- harmonics and L-Band signals.

The TW3440/TW3442 has a 19mm (3/4 Inch) though hole, permanent mount white-metal base, with an industrial-grade, IP67 compliant conical radome. Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0)
