True or false: someone has coined a name for the next member of the frequency system after this. 22:50, 6 Aug 2004 (UTC)

Yes, it's called infrared light. ;-)   radiojon 05:30, 2004 Aug 9 (UTC)

Would this heat-wave gun be an example of milimeter-wave technology? If so, should the article reference the prototype? -P-

Yep. Since it uses a 3mm wave.

Woah- it says that weapon is not painful. Every news report says it is extremely painful. —Preceding unsigned comment added by Furbybrain (talkcontribs) 19:39, 4 May 2008 (UTC)

Exposure to 3mm waves is shown to be painful and causes heat-burns when exposed in high-power 3mm.

Cleanup needed[edit]

This article needs a cleanup. All radio band articles (VLF LF MF HF VHF UHF SHF EHF) should be structured in the same way. --HelgeStenstrom (talk) 11:17, 18 September 2008 (UTC)

In general, I agree. --ChetvornoTALK 19:47, 8 March 2013 (UTC)

Can someone clarify if this means a kilometer above the ground or a kilometer in distance of transmission. If it is distance I think this is incorrect and possibly meant under about a kilometer? "Therefore, they have a short range and can only be used for terrestrial communication over about a kilometer." — Preceding unsigned comment added by (talk) 17:03, 14 September 2015 (UTC)

Name change[edit]

This article should be called "Millimeter-waves", since that is the name used everywhere (except on WP). Calling it "Extremely high frequency" is anachronstic. Setreset (talk) 08:12, 8 March 2013 (UTC)

"Extremely High Frequency" or EHF is the official designation of this band by the International Telecommunications Union (ITU) standards body 1 the same as VHF or UHF are for those bands. The term "extremely high frequency" seems to be widely used in professional electrical engineering literature. However, maybe the name "millimeter waves" should be moved up into the lead sentence. --ChetvornoTALK 19:46, 8 March 2013 (UTC)

WiMedia Alliance[edit]

This alliance no longer exists and the reference cited is a dead link. Sooku (talk) 20:03, 8 August 2014 (UTC)

Recent additions on health effects[edit]

Recently an editor has been repeatedly adding content on health hazards of the EHF radiation used in the Active Denial System, and health hazards of radio waves in general, to the Weapons systems section. While I think this material is important, I feel it is too general and WP:OFFTOPIC for this article. The material pertaining to the Active Denial System probably belongs in that article. The material on health hazards of cellphones certainly does not belong here because cellphones do not use the EHF band, it could perhaps be put in Cell phone. Alternatively, it could all go in Electromagnetic radiation and health. --ChetvornoTALK 17:04, 2 February 2015 (UTC)

External links modified[edit]

Hello fellow Wikipedians,

I have just added archive links to one external link on Extremely high frequency. Please take a moment to review my edit. If necessary, add {{cbignore}} after the link to keep me from modifying it. Alternatively, you can add {{nobots|deny=InternetArchiveBot}} to keep me off the page altogether. I made the following changes:

When you have finished reviewing my changes, please set the checked parameter below to true to let others know.

Question? Archived sources still need to be checked
