TW3101 Non Magnetic GPS L1 Antenna
The TW3101 by Tallysman Wireless is a precision
grade, permanent mount GPS L1 antenna with no
magnetic properties, specially designed to be used in
close proximity with compass based instruments.
The TW3101 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 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.
TW3101 Dimensions (mm)
Low Profile Radome shown. Conical Radome also available
The TW3101 is housed in a permanent mount
industrial-grade weather-proof enclosure and two
options for pole mounting are available an L-bracket
(P/N#23-0040-0) or a pipe mount (P/N#23-0065-0).
