... that we got 2187 hits? Less than amazing but clearly ahead of the other six DYK articles competing for attention - and that with being third on the list and not getting the picture. -- catslash ( talk) 02:21, 3 December 2010 (UTC)
The choke flange is a clever idea. It would be interesting to know who thought of it. Old Aylesburian ( talk) 10:19, 2 December 2010 (UTC)
This is slightly off-topic; discussion of pressurization probably belongs on the waveguide (electromagnetism) page. However, as I've just reverted an edit, I'll expand on my reasons. As a quick trawl of the web will convince you, pressurization of waveguides is nor restricted to outer space. High-power ground-based systems such as radar feeds are often pressurized. In the past an atmosphere of sulphur hexafluoride was used, but I'm not sure if this is still allowed. Also low-power outdoor installations are are often (slightly) pressurized with dry air to prevent the ingress of moisture (as was recently pointed out [1] by 98.81.3.202 ( talk)). Also pressurization is used in airborne systems. I may amend the text here, to mention exclusion of moisture. -- catslash ( talk) 22:43, 18 April 2012 (UTC)
