The main thing this article needs, I think, is at least a brief explanation of why a horn-shaped antenna is desirable. Any experts want to leap in and provide one? --

Well,
It tapers the wave impedance from that in the waveguide to that of free space, and so achieves a much better match (lower VSWR) than a simple open-ended waveguide.
It gives a larger aperture and hence a higher directivity than an open-ended waveguide (provided the taper is gradual enough that there isn't a large phase-variation over the aperture).
Incidentally: A portion of a waveguide in which the cross section is smoothly increased along the axial direction is a taper; I've never heard it called a horn. (Can't summon the enthusiasm to fix the actual article right now) --

I suggest removing content referring to acoustic horns, which is already covered in
horn (acoustic) and renaming this article
Horn antenna. Like
catslash I have never heard an internal taper in a waveguide called a "horn", in my experience the term "horn" in microwave engineering is used for horn antennas. --

The photo shown of a pair of Seattle Long-Lines horns are NOT Hoggs Horns; rather they are examples of a KS-15676 "Horn Antenna System" <
http://long-lines.net/tech-equip/radio/BSP402421100/p01.html> with a patent filing by Alfred C Beck and Harold T Friis (the wizard of radio-relay) November 26, 1941. Patent #2,416,675 granted and assigned to Bell Telephone Laboratories March 4, 1947...
I wrote the section on the Hogg antenna. You're right about the inventor, thanks for catching my screwup! I was able to find only brief articles about the antenna in technical books, and I thought I read that Hogg had invented it. Oops. The KS-15676 spec sheet you pointed out is fantastic!!!!! I tried to find info on those AT&T horn reflector antennas and couldn't find any. Horn reflector antennas like the KS-15676 are the same design as the
Holmdel Horn Antenna built by D. L. Hogg at Bell Labs in 1961, pictured in the article.
1. This design is referred to in microwave tech literature as the Hogg antenna. Apparently, although Beck and Friis invented it, Hogg got his name attached to it. --

The following is the content from the article titled "types of horn antenna". I did not feel that it could be simply pasted into the article, so I am posting it here in the remote chance that any of it is salvageable. I also cleaned it up a little bit.
The following discussion is an archived discussion of a

Support. This far more accurately describes the article's current content and focus, which fit in well with other related articles.

Support - for reasons already mentioned. Incidentally, there is also an article called
Feed horn. Also incidentally, a requested move may not be necessary; it's usually possible for an autoconfirmed user to move an article to a name currently belonging to a redirect page. --
