Overview

The TW2405/TW2407 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 multipath signal rejection.

The TW2405/TW2407 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. An optional tight pre-filter is available with part number TW2407 to protect against saturation by high level sub-harmonics and L-Band signals.

The TW2405 /TW2407 comes in a compact circular form factor with a built-in 56 mm diameter ground plane.

Also consider the TW2406/TW2408 which have a more secure mounting method. The TW2406/TW2408 is electronically identical to the TW2405/TW2407. The TW2406/TW2408 has a larger PCB with drilled holes for more secure mounting.
