## TW3752
## High Gain Multi-Constellation Antenna
> **Frequency Coverage:** GPS & QZSS L1 | GALILEO E1 | BEIDOU B1 | GLONASS G1
The TW3752 is a high-gain GPS + GLONASS + Galileo + BeiDou antenna specifically designed for timing applications in high density cell / telecommunications tower applications where high levels of near-out-of-band interfering signals can be expected.
The TW3752 covers the GPS-L1, GLONASS-G1, Galileo E1, BeiDou B1, and SBAS (WAAS, EGNOS & MSAS) frequency band and employs Calian's patented Accutenna® technology to provide excellent cross polarization rejection and greatly enhanced multipath rejection.
The TW3752 features triple SAW filters including a tight, low loss pre-filter to protect against saturation by high-level subharmonic and L-Band signals. This antenna also features a 50 dB LNA gain to handle the long cable runs sometimes associated with telecommunications towers.
The TW3752 housing has a permanent-mount, IP69K compliant metal base, and an extended temperature range plastic radome, and is specifically designed to withstand the most challenging environmental conditions.
Two options for pole mounting are available an L-bracket (P/N# 23-0040-0) or a pipe mount (P/N# 23-0065-0).
## Applications
