A Tallysman Accutenna®
TW2100 /TW2102 Magnet Mount Dual Feed GPS L1 Antenna
The TW2100 / TW2102 employ Tallysman’s
unique Accutenna technology in a magnet mount
GPS L1 antenna, specially designed for industrial,
agricultural and military precision positioning and
timing applications.
The antennas feature a custom high performance,
dual-feed, wide band patch element. Its LNA
configuration provides a LNA for each feed, a mid

section high rejection SAW for the combined
signal, followed by a final stage of LNA. It provides
±10MHz bandwidth centred on 1575.42 MHz and
covers
all
GPS
L1,
and
SBAS
(WAAS/EGNOS/MSAS) signals. It features great
axial ratio over the entire frequency range (<3dB),
excellent circular polarized signal reception, great
multipath rejection and out-of-band signal
rejection.
The TW2102 has a pre-filter to provide strong
protection against near frequency and harmonic
signals.
Dimensions (mm)
The antennas are housed in a compact, industrial-
grade weather-proof, magnet mount enclosure and
a wide range of connector.
