The "twist" in the radio waves is "Orbital Angular Momentum". If you're interested in a more technical explanation of this phenomenon, take a look at the following document to be published in the IEEE Transactions on Antennas and Propagation: http://www.lunduniversity.lu.se/o.o.i.s?id=24732&postid=2062936 The paper is a little hard to follow with all it's equations. The conclusion is that using Orbital Angular Momentum provides no more bandwidth than using MIMO (Multiple in multiple out) techniques. Griff W5VWP On 03/02/2012 02:00 PM, Michael James Hauan wrote:
