Narda, an L-3 Communications company, introduced a family of standard gain horn antennas for EMI and EMC testing applications that cover every waveguide band from 2.6 to 40 GHz.

The 600 Series horns include seven standard models that cover 2.6 to 3.95 GHz, 3.95 to 5.85 GHz, 5.4 to 8.2 GHz, 8.2 to 12.4 GHz, 14 to 18 GHz, 18 to 26.5 GHz and 26.5 to 40 GHz. Directivity patterns for all models include a beamwidth in the E and H planes from 23 deg. at 40 GHz to 34 deg. at 2.6 GHz. Sidelobes in the H plane are more than 20 dB down and first sidelobes in the E plan are 13 dB down and second sidelobes are 18 dB down.

Gain at mid-frequency is 16.5 dBi +/-1.5 dB over the operating bandwidth. VSWR of all models is 1.15:1 or less, and weight ranges from 6 lb. for the 2.6 to 3.95 GHz model to 4.5 g for the 18 to 40 GHz model. The Narda 600 Series horn antennas are supported by a variety of waveguide-to-coax adapters for either Type-N female or SMA/3.5/2.9 mm female connectors. All models are available for immediate delivery.
