This page needs an illustration or two of a vacuum variable capacitor. I have one and can photograph it and add the photo.
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)
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. Spinning Spark 15:23, 21 December 2016 (UTC)
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)
