Horn Antenna – The energy of the beam when slowly transform into radiation, the losses are reduced and the focussing of the beam improves. A Horn antenna may be considered as a flared out wave guide, by which the directivity is improved and the diffraction is reduced. One of the first horn antennas was constructed in 1897 by Bengali-Indian radio researcher Jagadish Chandra Bose in his pioneering experiments with microwaves. The modern horn antenna was invented independently in 1938 by Wilmer Barrow and G. C. Southworth. This Horn model antenna is suitable employed in the UHF or SHF radio bands. Making this horn model antenna it will be easy for a beginner to make if it works in the 10GHz frequency, because small dimensions so it is not so difficult and also offers gain up to 25dBi.

We are a small group of CW enthusiasts that happen to live in the state of Connecticut. Many of us are new to CW. Though some in our ranks have been at this for quite some time. We meet most nights online and about once a week in-person. You don’t have to live in Connecticut to join us, but it definitely makes it easier to meet in-person.
