Tallysman TW3150/TW3152 Timing Antennas

Click2Contact

The TW3150/TW3152 Timing Antennas, from Tallysman’s GNSS antenna range, are high-gain, high-rejection antennas designed for timing applications in high-density cell/telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected.

The antennas feature a 50 dB LNA gain to handle long cable runs often associated with installation on telecommunications towers. Covering GPS L1 and SBAS (WAAS, EGNOS and MSAS) frequency bands, the antennas employ Tallysman’s Accutenna technology to provide good cross-polarisation rejection and enhanced multipath rejection.

The TW3150 features a four-stage, dual-filtered LNA, while the TW3152 includes an additional SAW pre-filter to provide good 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.

The antennas’ housing has a permanent mount, IP67 and MIL-STD-801F Section 509.4 compliant metal base and a plastic radome with an extended temperature range. The housing is specifically designed to withstand challenging environmental conditions.

The antennas are REACH and ROHS compliant and there are two options available for mounting an L-bracket or a pipe mount.
