(Ottawa, Ontario, Canada, March 10, 2025) Calian GNSS is excited to announce that it has added the housed TW3885TL dual-band (L1/L5) Accutenna® technology timing antenna with a built-in lightning arrestor to its industry-leading line of GNSS products. The built-in lightning arrestor provides output protection (towards the GNSS receiver) from antenna lightning strikes, transients and surges up to 5 kA over 8/20 µs (IEC 61000-4-5).
The dual-band TW3885TL antenna supports GPS/QZSS L1/L5, Galileo E1/ E5a/b, BeiDou B1/B2/B2a, GLONASS G1/G3 and, in the region of operation, satellite-based augmentation systems (SBAS) [WAAS (North America), EGNOS (Europe), MSAS (Japan), or GAGAN (India)].
Historically, dual-band antennas and receivers commonly supported GPS L1 and L2 and GLONASS G1 and G2. In recent years, GPS, GLONASS, Galileo, BeiDou and NavIC have added GNSS signals in the L5 frequency band (1164-1217 MHz). As a result, a new dual-band GNSS standard has become L1 and L5. Calian’s new TW3885TL antenna has been tuned to provide optimal support for both the upper (L1/ G1/E1/B1/) and lower (L5/G3/E5/B2) GNSS bands.
The TW3885TL is housed in a through-hole mount, weatherproof (IP69K) enclosure. For permanent installations L-bracket (PN 23-0040-0) or pipe (23-0065-0) mounts are available. Calian GNSS provides an antenna installation guide which recommends a 100-125mm ground plane and provides antenna installation and cable connector waterproofing best practices.
The radio frequency spectrum has become congested worldwide as many new LTE bands have been activated, and their signals or harmonic frequencies can affect GNSS antennas and receivers. In North America, the planned Ligado service, which will broadcast in the frequency range of 1526 to 1536 MHz, can affect GNSS signals. New LTE signals in Europe [Band 32 (1452 – 1496 MHz)] and Japan [Bands 11 and 21 (1476 – 1511 MHz)] have also affected GNSS signals. Calian’s new TW3885TL mitigates the effects of these new signals.
Trust Calian GNSS to provide clean and pure GNSS signals in a noisy RF world.
