Tallysman Introduces a Family of High Gain / High Rejection Timing Antenna Print E-mail
Written by Tallysman   
Wednesday, 30 September 2015

Ottawa, Canada – September 30, 2015 – Tallysman™, a leading manufacturer of economical high performance GNSS antennas, is pleased to announce the availability of a family of high gain (50dB) and high rejection timing antennas. These antennas are specifically designed for timing applications in High Gain / High Rejection Timing Antenna (grey conical radome also available)high density cell / telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected. This antenna features a 50dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.

The TW3150/52 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 TW3150 features a four (4) stage dual filtered LNA, while the TW3152 includes an additional SAW pre-filter to provide exceptional rejection of close out-of-band signals and additional protection against saturation by high level sub-harmonic and L-Band signals. This provides better than 80dB of signal rejection above 1610MHz and below 1545MHz.

The antennas have a permanent mount, IP67 and MIL-STD-801F Section 509.4 compliant housing with metal base and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.

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

These antennas are REACH and ROHS compliant.
