Standard Gain Horn Antenna
Description
Standard Gain Horn Antenna is designed for accurate gain measurement and stable radiation performance across a defined frequency band.
With well-controlled beam pattern and predictable gain, it is widely used as a reference antenna in antenna testing, calibration, and measurement systems.
Features & Customization
Frequency range: 18 GHz–1100GHz, full waveguide bandwidth coverage.
Nominal gain:20-25 dB
High-precision EDM machining for structural accuracy and repeatability.
Stable performance with low reflection and high polarization purity.
Customizable gain, flange type, surface treatment, and material upon request.
