Lurker Posted May 4, 2019 Report Share Posted May 4, 2019 Tallysman, a leading manufacturer of high performance GNSS and Iridium antennas, is announcing the first three products of a new range of helical antennas to be introduced in 2019. The first three models of the Tallysman helical family are: HC871 (25g) – A housed, dual band, active GNSS antenna, supporting GPS L1/L2, GLONASS G1/G2, Galileo E1, and BeiDou B1. HC872 (36g) – A housed, dual band, active GNSS antenna, supporting GPS L1/L2, GLONASS G1/G2, Galileo E1, BeiDou B1, and L-Band services. HC600 (18g) – A housed, passive Iridium antenna. The active GNSS helical antennas feature an industry-leading low current, Low Noise Amplifier (LNA), and include integrated low-loss pre-filters, to protect against harmonic interference from high amplitude interfering signals, such as 700MHz band LTE and other near in-band cellular signals. Available in both housed and embedded OEM versions, the lightweight Tallysman helical antennas have excellent axial ratios, making them ideal for a variety of high-precision Unmanned Aerial Vehicle (UAV) applications. Tallysman is announcing the availability of its first three models of the helical family, with additional of models to be announced in Q3 2019 and onward. sources: https://www.geospatialworld.net/news/tallysman-introduces-lightweight-helical-gnss-and-iridium-antennas/ Quote Link to comment Share on other sites More sharing options...
