Tallysman Introduces High-Gain, High-Rejection Timing Antennas

Antenna maker Tallysman announces the availability of a family of high-gain (50 dB) and high-rejection timing antennas.

The antennas 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 50-dB LNA gain to handle long cable runs often associated with installation on telecommunications towers.

The TW3150/52 antennas cover the GPS L1 and SBAS (WAAS, EGNOS and MSAS) frequency band and employ Tallysman’s unique Accutenna technology to provide excellent cross-polarization rejection and greatly enhanced multipath rejection.

The TW3150 antenna features a four-stage dual-filtered LNA, while the TW3152 antenna 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 80-dB of signal rejection above 1610 MHz and below 1545 MHz, Tallysman said.

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).

The new antennas are REACH and ROHS compliant.
