A Tallysman Accutenna®
TW3100 / TW3102 Permanent Mount GPS L1 Antenna
The TW3100 and TW3102 employs Tallysman’s unique
Accutenna technology in a permanent mount GPS L1 antenna,
specially designed for professional precision tracking and
timing applications.
The TW3100 features 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, Galileo E1 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.
TW3100 Dimensions (mm)
The TW3102 has a prefilter to provide additional protection
from high power near frequency or harmonic signals.
The TW3100 is housed in a permanent mount industrial-
grade weather-proof enclosure.
two options for pole
mounting are available an L-bracket (P/N#23-0040-0) or a
pipe mount (P/N#23-0065-0)
