Description
OBH-180400-15 double ridge horn antennas operate broadband from 18GHz to 40GHz. The antenna supports linear polarized waveforms. This antenna is appropriate for the test of wireless and telecom communication antennas. High gain and low VSWR permit the measurement of weak signals and the generation of high field strengths without any significant return loss.
OBH-180400-15 is calibrated individually in line with ANSI C63.5-2006, making the antennas ideal for EMC/RF measurements. OBH-180400’s radiation pattern contains only one single main lobe over the entire frequency range without any other side lobes. The antenna is low weight within 0.5kg and has a rugged construction.

Mark Bennett –
We adopt this OBH-180400-15 horn antenna for our millimeter-wave EMC compliance testing. It delivers steady 13–16dBi gain across 18-40GHz, and typical VSWR is only 1.5:1 with max VSWR 1.8, signal reflection is extremely low. Linear polarization with high purity greatly stabilizes our FCC and MIL-STD test data, each antenna comes with separate calibration files.
Clara Foster –
Perfect wideband antenna for our SAR radar prototype testing. The consistent high gain and ultra-low VSWR eliminate signal distortion in Ka-band frequency range. Its lightweight rugged body is easy to mount on test turntables, cross polar isolation meets our military-grade EW measurement standards completely.
Julian Reed –
Great choice for TEMPEST and VDE lab measurement work. Flat gain performance throughout 18–40GHz spectrum, low VSWR minimizes power loss during transmit-receive cycles. Independent calibration for every unit ensures high repeatability of test results, far outperforms our previous narrowband horn antennas.
