The Triple-Band Anti-Jamming Antenna BNT009ProG1 is designed for drones, UGVs, and unmanned vessels that need reliable GNSS positioning when interference is present. This FAQ-style guide answers the practical questions integrators ask before choosing, mounting, and testing this 8-channel unit.
What Is the Triple-Band Anti-Jamming Antenna?
The Triple-Band Anti-Jamming Antenna is a compact GNSS protection terminal with an 8-channel array, nulling processor, and multi-constellation receiver support. It is built for platforms where GPS/BDS/GLONASS/Galileo reliability is critical.
Unlike a basic patch antenna, this unit actively suppresses interference before passing a clean signal to the receiver. It measures 150 × 130 × 21 mm, weighs ≤400 g, and consumes ≤12 W at room temperature. For full product details, see the BNT009ProG1 triple-band anti-jamming antenna product page.

Which GNSS Bands Does the Triple-Band Anti-Jamming Antenna Support?
The Triple-Band Anti-Jamming Antenna covers BDS-B1i at 1561.098 MHz, GPS-L1 at 1575.42 MHz, GAL-E1 at 1575.42 MHz, and GLONASS-G1 at 1602 MHz. This multi-constellation coverage gives redundancy when one band is disrupted.
| System | Band | Frequency |
|---|---|---|
| BeiDou | BDS-B1i | 1561.098 MHz |
| GPS | L1 | 1575.42 MHz |
| Galileo | E1 | 1575.42 MHz |
| GLONASS | G1 | 1602 MHz |
Why Do 8 Channels Matter?
Eight channels give the Triple-Band Anti-Jamming Antenna finer null resolution and more degrees of freedom than typical 4-element designs. That helps it handle complex interference patterns and multiple sources in urban or industrial RF environments.
More channels also support band-specific processing. Each channel can be optimized for its frequency range, which improves cancellation without cross-band interference.
How Much Jamming Suppression Does It Offer?
The unit provides ≥105 dBc single-jammer suppression and ≥95 dBc three-jammer suppression. In practical terms, this Triple-Band Anti-Jamming Antenna is intended for platforms that cannot tolerate loss of GNSS lock during critical missions.
What Interference Types Can It Handle?
The adaptive nulling engine is designed for white noise, spread-spectrum, pulse, sweep, and mixed interference. It detects and adjusts automatically, so operators do not need to manually configure a nulling strategy for each scenario.
What Power and Mounting Does It Need?
The Triple-Band Anti-Jamming Antenna accepts 5–17 V DC, with 12 V recommended. It includes reverse-polarity and over-voltage protection. Mounting uses M3 screws through a 4-hole flange, and the RF output is via SMA.
For installation, secure the flange to the airframe or vehicle, connect power through the J30J-9ZK connector, and choose either TTL serial NMEA0183 output or SMA RF output to your receiver. Do not supply 5 V on the SMA line.
How Accurate Is Positioning Under Jamming?
With jamming present, horizontal positioning accuracy is ≤10 m. Without jamming, the unit achieves ≤1.5 m horizontal accuracy. Velocity accuracy is ≤0.2 m/s, and timing accuracy is ≤100 ns.
Can It Work With an Existing Receiver?
Yes. You can connect the SMA RF output to your receiver’s antenna input, or use the TTL serial output for NMEA0183 data. Firmware upgrades for the anti-jamming module and receiver are also supported through the TTL serial interface.
Why Choose This Triple-Band Anti-Jamming Antenna for UAVs and UGVs?
A Triple-Band Anti-Jamming Antenna like the BNT009ProG1 is useful for drone navigation security, UGV and unmanned vessel positioning, fleet tracking, precision timing, and autonomous logistics in RF-noisy areas. It combines multi-constellation support, 8-channel processing, and compact mechanical design.
Final Take
The Triple-Band Anti-Jamming Antenna BNT009ProG1 answers a clear integration need: protect multi-constellation GNSS in a compact, power-efficient package. With 8 channels, ≥105 dBc single-jammer suppression, and support for BDS, GPS, Galileo, and GLONASS, it is a practical choice for UAVs, UGVs, and other autonomous platforms facing real-world interference.
