Chapter 6 is all about phased arrays of verticals, and the great thing is that you can do a cheapie phasing setup with only coax and so "T" connectors to get started. There is also a schematic for a relay box for switching the pattern if you want to automate. If you are really in a hurry to automate check out this site for a commercially made phasing setup: http://www.comteksystems.com/ click on the ACB-4 link and check it out. It is a 360 degree phasing setup! be sure to look at the customer photos of some nice array designs. Have fun !
