The 400–1600 MHz helical antenna is designed for video channel detection and radio monitoring in the lower-frequency range. Its 0.4–1.6 GHz operating range supports a wide variety of signals, from professional radio channels to video transmission systems.
The gain varies depending on frequency:
3.5 dB at 0.5 GHz
6.6 dB at 0.9 GHz
11 dB at 1.6 GHz
The radiation pattern varies from 85×85° to 40×40°, allowing either a wider or narrower field of view. Right-hand circular polarization improves reception efficiency and reduces interference from signals with opposite polarization.
The antenna supports power levels of up to 50 W and has a low standing wave ratio (<2), ensuring stable impedance matching with transmitting equipment. Its dimensions of 250 × 250 × 60 mm make it suitable for integration into both stationary and mobile systems.
Applications
- Video channel detection and radio environment monitoring across 400–1600 MHz
- Radio monitoring and spectrum control
- Electronic surveillance systems
- Facility security and protection systems
- Scientific and research projects
- Mobile and stationary receiving stations
The antenna is effective for accurate signal source detection and operation in high-interference environments.
