GNSS antennas
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 multi-constellation tracking 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, and SBAS (WAAS/EGNOS/MSAS) signals.
The TW7972 has a side connector which may not be suitable for all applications. The TW3972 has similar performances but with a through-hole connector.

We sell these antennas with a 100mm ground patch included.
Mechanical drawing
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).
VSP6037L and VSP6037L-MAR | Verostar Survey Grade Antenna
The VSP6037L is a survey grade antenna, capable of tracking all signals in view, and featuring maximal performance when centimeter level precision matters.
The VSP6037L-MAR is a special version of the VSP6037L with extra filtering that provide enhanced Iridium and Inmarsat signal rejection. Those signals which are typically found onboard large vessels or in harbors are close to GNSS signal and can disturb it.
Aside from this difference, both versions of the antenna share the same characteristics.
Those antennas feature a tight phase center variation and can be mounted on any standard survey mount with its 5/8"-11 UNC threaded hole.
