The TW1015 features a high performance custom tuned ceramic patch element, a very low noise amplifier (LNA) and a tight bandpass SAW filter. It covers the GPS L1 and SBAS (WAAS /EGNOS/MSAS) frequency band (1572.5 to 1578 MHz), and it offers great circular polarized signal reception, multipath rejection and out of band signal rejection.

The TW2015 comes in a compact circular form factor with a built-in 50 mm diameter ground plane, and with a 15 cm RG174 cable.

The TW1015 LNA gain is optimised to capture the LNA noise figure for OEM applications.

The built-in 35mm circular ground plane can be augmented with host system ground surfaces.

Tallysman offers custom services to assist with integration of the OEM module into end user solution.
