In today’s crowded radio spectrum, securing a stable satellite fix is tougher than ever. Standard single-band antennas often struggle when facing advanced electronic interference or challenging atmospheric conditions. The BNTWL880 Dual Frequency Eight-channel Anti-Jamming Antenna steps in to solve this. By combining multi-band tracking with a powerful eight-channel array, it delivers the high-precision data needed for mission-critical operations.

Broadened Frequency Coverage

What sets this unit apart is its dual-frequency capability. The BNTWL880 covers BDS_B1, GPS_L1, GAL_E1, along with the secondary frequencies BDS_B2, GPS_L5, and GAL_E5. If your project requires extra redundancy, optional modules for GPS_L2 and BDS_B3 are available. Tracking two frequencies simultaneously (such as L1 and L5) allows the receiver to correct ionospheric delays. This results in significantly better positioning accuracy compared to single-band solutions. The antenna locks onto multiple constellations at once, giving your system a much richer pool of satellite signals to work with.

Robust Jamming Resistance

When hostile or accidental interference hits, this antenna stands its ground. The integrated eight-channel digital processing system provides an outstanding anti-single broadband interference capability of ≥110dB. Even against complex threats, it maintains a solid anti-seven broadband interference capability of ≥95dB. The internal spatial filtering creates “nulls” toward jamming sources, effectively deafening the antenna to noise while keeping the actual GNSS signal intact. This automated defense runs constantly in the background, ensuring your receiver never loses the lock due to sudden RF bursts.

Slimmer, Hardened Hardware Design

Despite the dual-frequency complexity, the physical footprint remains manageable. It uses a low-profile cylindrical housing measuring Φ240.0mm × 42.0mm and weighs just ≤1.55kg. The flat, disk-like shape makes it particularly easy to mount on vehicle roofs and marine vessels without creating a massive aerodynamic drag. Power consumption is rated at ≤29W, reflecting the extra processing required for dual-band operations, yet it remains efficient for mobile deployments. The rugged exterior protects the internal electronics from dust, rain, and constant vibration.

Where the BNTWL880 Excels

This hardware is built for demanding environments. It’s an excellent choice for surveyors needing centimeter-level accuracy in remote areas. In agriculture, it guides heavy machinery with pinpoint precision. For defense and security, the high interference thresholds guarantee that vehicles and stationary bases stay connected to navigation networks even when adversaries deploy jammers. The anti-jamming antenna is ready to integrate straight out of the box with your existing receiver setups.

Final Thoughts

You don’t have to accept navigation dropouts. The BNTWL880 Dual Frequency Eight-channel Anti-Jamming Antenna gives you dual-band accuracy and military-grade signal protection in one compact unit. It’s a practical, heavy-duty upgrade for anyone who relies on trustworthy positioning data.

What does "dual frequency" actually mean for this product?
It means the antenna can receive and process signals from two different frequency bands at the same time, such as L1 and L5, which helps eliminate atmospheric errors.
Can I upgrade the frequency points later?
The optional GPS_L2 and BDS_B3 modules must be requested at the time of order; they are not user-installable afterward.
How is this different from your standard single-frequency eight-channel model?
This model handles twice the frequency bands, has a wider physical diameter to house the larger array, and requires slightly more power to process the extra signals.
Does the low-profile shape affect signal reception?
Not at all. The internal patch elements are tuned specifically for this Φ240mm housing to maintain optimal gain.
How much power does it draw during idle time?
Power consumption is capped at 29W during full processing load, and it remains well within that limit during idle.
What kind of connectors are on the bottom?
It comes with standard RF connectors (typically TNC or SMA) suitable for most professional GNSS receivers.
Will it work if I mount it on a metal roof?
Yes, the base is designed to provide a proper ground plane for the antenna array when mounted on metal surfaces.
Can it handle vibrations from a moving tractor or truck?
The solid-state internal design and rugged exterior are built to withstand continuous heavy vibrations.
Is there any special maintenance required?
No. Just keep the top dome clean from thick mud or snow, and the internal electronics will handle the rest.
Does it support anti-spoofing as well as anti-jamming?
The primary focus is on broadband jamming suppression (up to 110dB). For spoofing, you would need to pair it with a receiver equipped with spoofing detection.
