Talk:Vacuum variable capacitor

This page needs an illustration or two of a vacuum variable capacitor. I have one and can photograph it and add the photo.

Change name to Vacuum capacitor?
As it is currently named, this article excludes fixed value vacuum capacitors, which are also widely used in addition to the variable types. We certainly don't need two separate articles, so I think this article should be moved to the more inclusive term Vacuum capacitor, with Vacuum variable capacitor as a redirect. -- Chetvorno TALK 11:05, 7 September 2014 (UTC) I don't know about variable vacuum capacitors, but Eimac advertised fixed as early as 1938. — Preceding unsigned comment added by 72.128.92.30 (talk) 13:24, 8 April 2016 (UTC)
 * Yes, I fully agree, it is the very much better term. I can complete the article in a few month, adding missing parts which are described already in the German article. --Elcap (talk) 12:13, 7 September 2014 (UTC)
 * What is the status of this suggestion? Nobody has spoken against it.  If nobody objects, then I'll try to move it in a few days (if I remember, and if I have authority). LachlanA (talk) 04:11, 20 September 2018 (UTC)

Comparison
A lot of the comparisons in this section are really false comparisons. The advantages stated of protection against ingress of dust and insects are the advantages of a sealed capacitor over an unsealed one. One can just as easily (more easily even) seal an air dielectric capacitor and get the same advantages. SpinningSpark 15:23, 21 December 2016 (UTC)
 * The comparison is unnecessary. The applications of vacuum types are high professional transmitters, measuring equipments and other expensive devices. Air types formerly are used in radios, nowadays maybe in cheaper measuring equipments or faced out by semiconductor solutions. --Elcap (talk) 09:54, 27 December 2016 (UTC)

Invention
A link or reference to the particular patent by Tesla would be useful. I have investigated his patents, and have so far been unable to find the one referenced. One with the title in quotes, "Apparatus for producing electric currents of high frequency and potential," mentions only the potential of using the device to make a vacuum ("vacua"). Two of his condenser patents mention the importance of removing air, but by replacing it with fluid (oil), not a vacuum. AceNZ (talk) 01:21, 25 August 2018 (UTC)
