Tallysman TW3142 GPS Timing Antenna

Tallysman TW3142 High Gain Timing Antenna

The TW3142 from Tallysman is a high-gain GPS antenna specifically designed for applications in environments where high levels of nearout-of-band interfering signals can be expected.



The TW3142 from Tallysman is a high-gain GPS antenna specifically designed for timing applications in high density cell / telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected. This antenna features a 40dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.

The TW3142 covers the GPS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band and employs Tallysman’s unique Accutenna technology to provide excellent cross polarization rejection and greatly enhanced multipath rejection.

The TW3142 housing has a permanent mount, IP67 compliant metal base, and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.

The antenna is RoHS, REACH, and RED compliant.

Two options for mounting are available: an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
