Description & Specification

HB-07M18G-NF Double Ridged Horn Antenna

700 MHz - 18 GHz | 300W CW | Ultra-Wideband Reference

The HB-07M18G-NF is a high-performance Open Boundary Double Ridged Horn Antenna designed for broadband applications ranging from 700 MHz to 18 GHz. This ultra-wideband capability allows it to replace multiple narrowband antennas in EMC/EMI test setups. Constructed from 6061 Aluminum alloy with a Stainless Steel N-Female connector, it features a DC Short circuit design for lightning protection and is capable of handling up to 300 Watts (Continuous), making it an ideal choice for radiated immunity testing and high-power measurements.
