Did you miss our In-Person Short Course? Technical and engineering professionals who are looking to expand their knowledge of antenna measurements can do so with the help of NSI-MI's Virtual Short Course. Plus, additional add-on modules.

NSI-MI designs and manufactures specialized RF Scene Generators™ to create user-controlled simulations of complex real-world RF environments.

At the NSI-MI Store, we offer a wide range of antennas and probes to assist you with your antenna testing requirements. 

NSI-MI Quad Ridged Feeds (ANT-QRF) are used in antenna test range applications and have been designed to deliver a wideband frequency response.

This broadband ridged antenna is the perfect choice for spherical near-field measurements and far-field range illumination. With its wide frequency bandwidth, it can replace several standard Open-Ended Waveguide probes or horns.

This system can measure antennas from 18.0 to 110.0 GHz with payloads of up to 0.5 m (19.7 in.) in diameter and 75 kg (165 lb). Plus, the base, reflector, and positioning system come pre-assembled, aligned, and integrated with the chamber.

Our range of standard gain horn antennas are used in antenna test range applications and have been designed to deliver accurate gain reference and reliable antenna gain measurements. 

NSI-MI Technologies’ line of Active Antenna Load Management (AALM) products maintains the anechoic integrity of a test environment while managing the radiation load when testing active antennas with on-board amplifiers.

NSI-MI Technologies’ rotary positioners are engineered to provide the optimum balance of outstanding performance, maximum power-density, and excellent application flexibility. 

AMETEK NSI-MI’s portable target simulation compact ranges uses the most advanced technology. We offer custom systems for simulating missiles, decoys, and more.
