TW3030 Permanent Mount GPS L1 Antenna
The TW3030 by Tallysman Wireless is a
professional grade, permanent mount GPS L1
antenna, specially designed for professional
precision timing applications.
The TW3030 features a custom high performance,
wide band patch element, a 30dB gain LNA stage
and a high rejection out-of-band SAW filter. It
provides ±10MHz bandwidth centred on 1575.42
MHz and covers the GPS L1, Galileo E1 and SBAS
(WAAS/EGNOS/MSAS) signals. It provides great
axial ratio, excellent circular polarized signal
reception, great multipath rejection and great out-
of-band signal rejection.
The TW3030 is housed in a compact, industrial-
grade weather-proof, domed shaped enclosure. Its
radome is available in dark gray or white, it comes
with a TNC female connector and a L-bracket for
pole mount is available (P/N#23-0040-0).
