Horn Antenna 18-40 GHz Passive

The AH-840 is a broadband, linearly polarized double-ridge waveguide horn antenna operating over 18 GHz to 40 GHz.

It is suitable for both transmitting and receiving in EMI emissions and immunity testing.

The antenna is constructed from high-grade, corrosion-resistant aluminum and painted for additional protection.

It features a high-quality 2.92 mm (K-type) coaxial connector for secure and efficient signal transfer.

The AH-840 is capable of handling up to 10 watts with the adapter or 200 watts for direct waveguide connection.

It can generate field strengths of over 1,000 V/m at 1 meter with 200 watts of input power.

The antenna can be used as a substitution antenna for ERP and EIRP measurements of intentional radiators.

It complies with regulatory standards including FCC, CE, MIL-STD-461, RTCA DO-160, FDA, and ETSI.

Each AH-840 is individually calibrated per ANSI C63.5 with NIST traceability; ISO 17025 calibration is available.

It is designed for daily use in indoor or outdoor lab environments, even under harsh weather conditions.

The AH-840 supports mounting on a tripod or mast via a standard 1/4-inch x 20 threaded hole.

Additional uses include site comparisons, shielding effectiveness testing, field monitoring, and site surveys.
