A Tallysman
Accutenna™
TW2410/TW2412 Magnetic Mount GPS/GLONASS Antenna
The TW2410/TW2412 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 TW2410/TW2412 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 TW2412 to protect against saturation
by high level sub-harmonics and L-Band signals.

The TW2410/ TW2412 is housed in a compact,
industrial-grade weather-proof, magnet mount
enclosure, and is available with a variety of
connectors.
