## TW7900P 

## Multi-Constellation Triple-Band Passive Antenna 

**Frequency Coverage:** GPS L1, L2, L5 | GALILEO E1, E5a, E5b | BEIDOU B1, B2a, B2b | GLONASS G1, G2, G3 | NavIC L5 + L-Band 

The TW7972P is a precision-tuned triple-band, Accutenna® technology antenna for reception of GPS/QZSS-L1/L2/L5, GLONASS-G1/G2/G3, BeiDouB1/B2b, Galileo-E1/E5a/E5b plus L-Band corrections signals. The TW7972 provides superior multipath rejection and axial ratio, a linear phase response, and tight phase centre variation (PCV). 

This antenna is ideal for precision agriculture, autonomous vehicle tracking and guidance, and other applications where precision matters. 

The TW7972P is housed in a magnetic mount, weatherproof enclosure. Architecturally,it features a dual-feed circular stacked patch element. The signals from the two orthogonal feeds are summed in quadrature. 

A 100 mm diamter ground plane is recommended for optimal antenna performance. 

## Applications 

- Precision GNSS position 

- Triple-frequency RTK systems (base and rovers) 

- Positive Train Control (PTC) systems 

## Features 

- Axial ratio: < 2.0 dB typ. 

- Tight phase centre variation 

- ESD circuit protection (15 kV) 

- IP67, REACH, and RoHS compliant 

## Benefits 

   - Ideal for triple-band RTK systems 

   - Great multipath rejection 

   - Increased system accuracy 

   - Great signal-to-noise ratio 

- Safety & security 

- Precision agriculture
