Helical Multi-Frequency Active Antenna

The M9PLUS-HCT-A-SMA PLUS is an active multi-frequency, high-accuracy GNSS antenna designed to support L1/L2/L5 GPS, Galileo, Beidou, GLONASS bands, as well as L-band correction services. Built on Maxtena’s proprietary Helicore® technology, the antenna offers exceptional pattern control, polarization purity, and high efficiency in a compact form factor. The integrated pre-filter in this GNSS antenna is specifically designed to mitigate LTE interference, which is crucial for maintaining signal integrity in high-performance GNSS applications. LTE signals can often overlap with or interfere with GNSS frequencies, particularly near urban areas or in environments with dense mobile communication networks. By incorporating a pre-filter, the antenna effectively blocks out-of-band LTE signals, reducing the risk of intermodulation and maintaining clear, precise GNSS signal reception. This enhanced filtering improves signal-to-noise ratio (SNR) and enables more reliable satellite tracking, even in challenging RF environments, which is essential for applications requiring high accuracy and dependability. The antenna includes an integrated SMA connector and rugged, IP67 automotive-grade components, making it ideal for applications that demand high precision and minimal integration effort or for retrofitting existing products. The M9PLUS-HCT-A-SMA PLUS also features an O-ring for enhanced environmental sealing.
