RFlight EMC High-Gain Horn Antennas, 1–40GHz
RFlight high-gain horn antennas for radiated immunity and high-field testing from 1GHz to 40GHz in four bands, 11–21.5dB gain, for use with high-power EMC amplifiers.

Overview
Radiated immunity testing above 1GHz, and military and aerospace high-field testing such as MIL-STD-461 RS103, GJB151C and DO-160, needs an antenna that turns amplifier power into field strength efficiently and can handle that power continuously. RFlight's high-gain horns are built for exactly that role in RFlight's own EMC test systems and amplifier racks.
The range splits the spectrum into four bands. The NTANT-1060HS covers 1–6GHz with an N-type input; the NTANT-60180HS covers 6–18GHz on a WRD50 waveguide input with 19dB gain; the NTANT-180265HS (18–26.5GHz, BJ220) and NTANT-265400HS (26.5–40GHz, BJ320) extend coverage into the millimetre-wave bands. Higher gain means more field strength for the same amplifier power, so choosing the right horn directly affects how large an amplifier the test needs.
RFlight can customise antenna gain to suit a field-strength target. Pair these horns with RFlight power amplifiers to build a complete GJB151C 200V/m or 400V/m system.
