TW7972 | Triple Band Antenna with L-band | Side connector

These high performance antennas have been especially chosen for their excellent performance/size compromise.

The TW7972 provides a multi-constellation tracking , featuring capabilities, supporting a range of satellite systems including GPS L1/L2/L5, GLONASS G1/G2/G3, BEIDOU B1/B2/B2a, GALILEO E1/E5a/E5b, L-Band correction, as well as and SBAS (WAAS/EGNOS/MSAS) signals tracking.

The TW7972 has a side connector which may not be suitable for all applications. The TW3972 has similar performances but with a through the -hole connector.

Info

We provide only the flat radome version of the antenna.

Both the flat and conical radome have same performances. The conical radome is useful for applications where there is a risk for the accumulation of a substance on top of the antenna (such as snow).
