The TW2406 employs Tallysman’s unique Accutenna™ technology covering the GPS L1, GLONASS L1 and SBAS (WAAS, EGNOS & MSAS) frequency bands (1574 to 1606 MHz). It is especially designed for precision industrial, agricultural and military OEM applications. It provides truly circular response over its entire bandwidth thereby producing superior multi-path signal rejection.

The TW2406 features a dual-feed wideband patch element, with a two stage Low Noise Amplifier, comprised of one input LNA per feed, a mid section SAW to filter the combined output, and a final output gain stage.  This configuration provides excellent axial ratio that is constant across the full frequency band.

The TW2408 version offers an optional tight pre-filter to protect against saturation by high level sub-harmonics and L-Band signals.

The TW2406 | TW2408 is electronically identical to the TW2405 | TW2407 but has a larger PCB with drilled holes for more secure mounting.  Both versions come in a compact circular form factor with a built-in 56 mm diameter ground plane.
