Order high-performance Horn Antennas direct from Westek Electronics. Learn about power handling, beamwidth & gain for precise RF & EMC testing.
Choosing the right Horn Antennas is essential for accurate EMC and RF testing. Their directional design, broad frequency range, and reliable performance make them ideal for compliance, measurement, and calibration tasks. At Westek Electronics, we provide a wide range of antennas built to meet the demands of professional testing across Australia.
What Are Horn Antennas and Why Are They Crucial for EMC and RF Testing?
Horn Antennas are directional antennas with a flared metal waveguide design, enabling efficient RF signal transmission and reception. Their broad frequency range, stable gain, and low VSWR make them ideal for EMC and RF testing tasks like radiated immunity, calibration, and site validation. Known for their precision and reliability, they give engineers confidence in high-stakes testing environments.
Horn Antennas Available at Westek
At Westek Electronics, we offer a broad selection of high-performance Horn Antennas from leading global manufacturers. Our product range supports a variety of applications across numerous testing environments.
• Double-Ridged Horn Antennas – Like the BBHA 9120 series, it provides wideband coverage from 0.2 GHz to 40 GHz with low VSWR and gain up to 21 dBi. Built from durable aluminium, they’re ideal for high-performance EMC and RF testing.
• Standard Gain Horn Antennas – They offer stable gain (15–20 dBi) and low VSWR across 1 GHz to 40 GHz, ensuring reliable RF testing. With high-power connectors and durable aluminium build, they’re ideal for EMC applications like immunity testing and system calibration.
• Dual Polarised Horn Antennas – It covers 0.4 GHz to 10 GHz and supports both polarisation modes in one compact unit—ideal for MIMO and efficient testing. Lightweight and durable, they feature SMA or N‑type connectors for quick, reliable EMC and RF measurements.
• TEM Horn Antennas – Such as the TEMH 6000, offer 300 MHz to 8 GHz ultra-wideband performance with linear polarisation— these antennas are ideal for UWB and close-proximity testing. Built from aluminium with N‑female connectors, they handle up to 300 W and meet IEC 61000‑4‑39 standards.
Understanding Key Performance Metrics When Selecting a Horn Antenna
Selecting the appropriate antennas involves careful evaluation of core performance metrics. These factors directly influence the effectiveness and accuracy of your testing systems.
• Power Handling – Power handling defines the maximum RF power an antenna can withstand without damage. For EMC testing, especially radiated immunity, high power handling ensures reliable field strength. Our Horn Antennas support industrial-grade power for safe, long-term use.
• Beamwidth – Beamwidth is the angle of an antenna’s radiated field. Narrow beams offer focused measurements, while wide beams suit broader coverage. Knowing your beamwidth needs helps optimise antenna placement.
• Gain – Gain measures the antenna’s signal strength in a specific direction. High-gain antennas enhance long-range testing accuracy. We provide models with precise, documented gain specs.
