Talk:Horn antenna

message: 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. --ChetvornoTALK 01:37, 18 July 2010 (UTC)
replies: text: Agreed. Horn antenna already redirects here. Also the change would side-step the issue of whether a taper could be called a horn. --catslash (talk) 21:45, 18 July 2010 (UTC)
replies: text: Looking at this issue too. As we have Horn (acoustic) then I would suggest this article be left as is or renamed Horn (microwave). Horn (microwave) is, in my experience, a very common term for them, after all you do use horns at microwave frequencies don't you?.  Types of horn antenna should be merged in and redirected, though I doubt there is any useable content. - The stub Horn (telescope) exists, should probably be a wp:dab page. Feed horn might be merged too. ☢ 220.101 talk\Contribs 04:56, 27 September 2010 (UTC)
replies: text: Although horns are most commonly used at microwave frequencies, they are also used at UHF and millimeter wave frequencies, so I think Horn (microwave) would be inaccurate.  The title Horn antenna emphasizes its function and avoids specializing to a specific frequency range, and is what the device is called in engineering texts.  Horn (microwave) could be a redirect. --ChetvornoTALK 19:36, 12 November 2010 (UTC)
replies: text: The acoustic content has been moved to Horn (acoustic) and the article has been renamed Horn antenna.  --ChetvornoTALK 18:49, 20 November 2010 (UTC)
thread_title:  Rename this article [[Horn antenna]]? 

message: 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...

This was before the Hoggs design.  — Preceding unsigned comment added by 166.84.1.1 (talk) 00:23, 19 December 2011 (UTC)
replies: text: 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.  --ChetvornoTALK 05:41, 20 December 2011 (UTC)
thread_title: Incorrect reference

message: 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.
There are five types of horn antenna:
#Conical horn antenna:Conical horn antenna can be directly excited from a circular waveguide
#Ridge horns: Central ridge loads a waveguides and increases the bandwidth by lowering cutoff frequency of the dominant mode
#Septum horns
#Corrugated horns: Corrugated horns can provide reduced diffraction, improved pattern symmetry and reduced cross polarization
#Aperture-Matched antenna
