Product Description

Directional Antenna Of Vehicle-mounted Interferometer

Product Overview
The 8-18 GHz Broadband Direction Finding Antenna is a high-performance, wideband antenna designed for spectrum monitoring, signals intelligence (SIGINT), electronic warfare (EW), and radar applications. Operating across the 8 GHz to 18 GHz frequency range (X-band and Ku-band), this antenna provides 360° direction coverage with vertical polarization and a characteristic impedance of 50Ω.

Engineered for professional DF applications, this antenna delivers a gain of ≥10 dBi (typical) across the entire operating band. Its compact dimensions (≤Φ60 × 40 cm) and lightweight design (≤15 kg) make it an ideal choice for fixed-site and mobile monitoring stations, as well as airborne and vehicle-mounted DF systems.

Key Features and Benefits
1. Wide Frequency Coverage (8-18 GHz)
This antenna covers the 8 GHz to 18 GHz spectrum, encompassing:

X-Band: 8-12 GHz (Radar, Satellite, Medical)
Ku-Band: 12-18 GHz (Satellite, Radar, EW)
This single antenna replaces multiple narrowband antennas, simplifying system design and reducing installation costs.

2. High Gain (≥10 dBi)
The antenna provides a gain of ≥10 dBi (typical value, 8 GHz to 18 GHz), ensuring effective signal reception across the entire operating band.

3. 360° Direction Coverage
The antenna provides 360° direction coverage, making it ideal for DF systems that need to detect and locate signals from any direction without mechanical rotation.

4. Vertical Polarization
The antenna uses vertical polarization, which is standard for most communication systems and ensures compatibility with existing infrastructure.

5. Excellent Standing Wave (≤2.5 Typical)
A Voltage Standing Wave Ratio (VSWR) of ≤2.5 (typical value) ensures good impedance matching, minimizing signal reflection and maximizing power transfer.

6. Flexible Output Interface
Direction Finding Output Interface: N-50K or SMA-50K available
This flexibility allows integration with a wide range of DF receivers and processing units.

7. Robust Construction
Dimensions: ≤Φ60 × 40 cm
Weight: ≤15 kg
Color: White for a professional, discreet appearance.
