In Reply to: Can't "waveguides" also be "horns", and vice-versa ? posted by peppy m. on April 2, 2021 at 10:26:36:
All horns are wave guides. Not all wave guides are horns. In order to have gain a horn throat must be less than a wavelength in dimension. You very much can have a horn that gives gain in the low end but not the high end, for that reason. A true wave guide has no gain, as the throat is too big for loading. But the main difference between a wave guide and a horn from a real world standpoint is what you call it, and why. Horns have an undeserved reputation for having a honking tone, making them a difficult sell to those who listen with their eyes rather than their ears. Calling horns wave guides is how the marketeers get around using the dreaded 'H' word.
