New High-Gain, High-Rejection GNSS Antennas From Tallysman
Tallysman, a manufacturer of economical high performance GNSS antennas, is rolling out a family of high-gain (50dB) and high-rejection timing antennas.
The TW3150 and TW3152 are 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. They feature a 50dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.
The antennas cover the GPS L1 and SBAS (WAAS, EGNOS & MSAS) frequency band and employ Tallysman’s Accutenna technology to provide first-class cross polarization rejection and greatly enhanced multipath rejection.
The TW3150 features a four-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 are specifically designed to withstand challenging environmental conditions.
Two options for mounting are available: An L-bracket or a pipe mount. The antennas are REACH and ROHS compliant.
Tallysman is a leading manufacturer of high performance, high quality products for a wide range of Global Navigation Satellite Systems (GNSS) applications. Tallysman’s mission is to provide GNSS antennas which meet the needs of a new generation of positioning systems providing unprecedented accuracy at ever decreasing prices. Tallysman is headquartered in Ottawa, Canada.
