7‑Band Directional Antenna for Drone Countermeasure
Product Introduction
In drone countermeasures, special communications, and spectrum control, it is often necessary to cover several critical frequency bands simultaneously while maintaining sufficient gain and directivity on each band. The 7‑Band Directional Antenna from Boges integrates seven independent ports into a single compact housing, covering seven commonly used bands from 824MHz to 5.85GHz. It offers an all‑in‑one antenna solution for anti‑drone guns, jamming devices, and multi‑band test systems.
Seven Independent Ports – Each Optimised for Its Band
The antenna integrates seven independent radiating elements, each optimised for a specific frequency band with minimal inter‑port interference. They can operate simultaneously or individually. Typical performance per port is as follows:

Excellent Directivity and Front‑to‑Back Ratio
- Typical front‑to‑back ratio (F/B) reaches 17–21 dB on Port 4 and 12–16 dB on Ports 5/6, meaning very strong rejection of signals coming from behind the antenna – effectively reducing feedback interference to the transmitter.
- Horizontal beamwidth varies from 20° to 216° depending on the band, allowing flexible main‑lobe coverage according to the target area.
Rugged and Reliable – Built for Harsh Environments
- Operating temperature: -40℃ to +85℃ – suitable for outdoor and severe conditions
- Storage temperature: -40℃ to +85℃, humidity ≤95%
- Reliability testing: Passed thermal cycling, damp heat, vibration, drop, pull force, and voltage withstand tests – ensuring long‑term stability
- Cable loss: High‑quality 086 coaxial cable with specified attenuation per band (e.g., ≈3.2dB/m at 2.4GHz, ≈4.8dB/m at 5GHz)
Typical Applications
- Drone Countermeasures (Anti‑Drone Guns)
Covers the most common drone communication bands (800/900MHz, 1.2/1.4GHz, 1.5/1.6GHz, 2.4GHz, 5.8GHz). The high‑gain directional radiation effectively jams drone video downlinks, flight control, and GNSS links.
- Spectrum Jamming & Interference Systems
Used in special communications, electronic countermeasures, exam hall shielding, etc. One antenna delivers multi‑band jamming signals simultaneously, simplifying system design.
- **Multi‑Band Directional Testing & Measurement
Acts as a standard transmit or receive antenna in EMC pre‑testing, antenna comparison, pattern measurement, and other lab applications – covering from cellular to Wi‑Fi bands.
- Specialised Communication Links
Provides high‑gain directional transmission/reception for point‑to‑point links that need to operate on several discrete bands simultaneously (e.g., broadband data + narrowband control).
