Tallysman, a manufacturer of high-performance GNSS antennas and related products, has released two high-gain (50dB) GNSS antennas: the TW3152 and TW3752. High-gain GNSS antennas are useful in situations where long cable runs are required, such as in timing systems and GNSS re-radiator systems, the company said. The TW3152 provides reception of GPS L1. The TW3752 provides reception of GPS L1, GLONASS G1, BeiDou B1 and Galileo E1 signals. Both antennas employ Tallysman’s Accutenna technology, which provides a high degree of multipath signal rejection through the full bandwidth of the antenna. According to Tallysman, the antennas are triple filtered to prevent the saturation of the front-end LNA by strong near frequency and harmonic signals, which are a growing concern throughout the world. These antennas are available with a choice of radome shape (flat or conical), color of radome (white or grey), as well as a wide variety of connectors.
