A Tallysman Accutenna® TW3150/52 High Gain / High Rejection Timing Antenna The TW3150/52 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 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 subharmonic and L-Band signals.. The TW3150/522 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. Two options for pole mounting are available an L-bracket (P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
