The FMWAN284-20 standard gain horn antenna (also known as waveguide horn) from Fairview Microwave has a nominal gain of 20 dBi. The Fairview Microwave 20 dBi WR-284 horn antenna operates from 2.6 GHz to 3.95 GHz (S Band). This WR-284 standard gain horn has a CMR-284 type flange. Waveguide standard gain horn antennas are used in a wide variety of applications due to their high power handling capability, low loss, high directivity, and near constant electrical performance. These units are Aluminum and Powder coated for increased resistance to weather and corrosion with a Horizontal and Vertical Beam Width of 17.5 and 17.3 degrees respectively.Fairview Microwave's WR-284 standard gain horns are available in 10, 15 and 20 dBi models with pyramidal shape and rectangular input. S Band standard gain horn antenna can ship the same day to anywhere in the world. The WR-284 FMWAN284-20 waveguide horn is part of over 40,000 RF, microwave and millimeter wave components available from Fairview Microwave.
