Poor article
The Wikipedia article on antenna engineering is of high quality, quite unlike this one which offers no theory whatsoever, nor any insight into how it could work. What's needed at the very least is an explanation of how a planar EM wave from a distant source is coupled by a wokfi antenna into the antenna of a USB dongle (said to be the typical use), along with calculations and/or measurements (ideally both) of directivity, efficiency. and (hence) gain. As the article stands, someone basing their antenna design on it could inadvertently build one with efficiency and/or gain worse than that of the unassisted USB dongle.
 * Design considerations for a cantenna are quite different, though that article has similar shortcomings to this one. Vaughan Pratt (talk) 23:58, 7 June 2015 (UTC)
 * I agree. The design of these DIY antennas shows an ignorance of basic electromagnetics.  It looks like college students have simply picked up anything that looked vaguely like a parabolic dish and used it.  In order to get any kind of directivity, the aperture of a parabolic antenna needs to be large compared to the wavelength λ; it should be at least >10λ.  At the 12 cm (2.4 GHz) and 6 cm (5 GHz) wavelengths used for Wifi, a wok would be only 4-8λ and a typical pot lid would be even less.   On 2.4 GHz the lid is probably going to couple to the feed antenna as a parasitic element, instead of acting as a reflector.  At these apertures the parabolic shape gives absolutely no gain advantage.  A flat cookie sheet placed behind the dongle would probably give comparable gain, or perhaps two cookie sheets at right angles to make a corner reflector antenna.


 * As you say, some technical data would make this a much better article. With their wide use, there must be performance data and design info for DIY Wifi antennas out there.    I don't have time to look into this now, maybe you can. Cheers. -- Chetvorno TALK 07:14, 8 June 2015 (UTC)

External links modified
Hello fellow Wikipedians,

I have just added archive links to 2 one external links on WokFi. Please take a moment to review my edit. If necessary, add after the link to keep me from modifying it. Alternatively, you can add to keep me off the page altogether. I made the following changes:
 * Attempted to fix sourcing for http://www.peteredge.orcon.net.nz/wokfidownsouthedit.html
 * Added archive https://web.archive.org/20140817040813/http://www.usbwifi.orconhosting.net.nz/ to http://www.usbwifi.orconhosting.net.nz/

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