So I  was wondering if aluminum foil could be wrapped around cables to reduce RF interference. I googled it. Apparently it might help, but there might be some concern with the cables getting warmer than usual. Having stated this, I wonder if the interference at the plug is the main problem.
Also, if one were really clever, once could experiment with creating a little mini, concave RF reflector out of aluminum foil, to effectively make the Mac's wifi antenna more directional. While making a little pedestal out of Legos the curved strip of foil could be placed under the computer vertically, behind the wifi antenna, and directed towards the wifi router. I can't imagine it would help much, but since the author already has an RF meter, it might be worth the experiment.

Every person reading this article is wondering why you aren’t recommending some cables to use. 

Actually, I was wondering more about what could be done to shield existing cables better.
