[TowerTalk] 4 square

[Dan Maguire]

For Rex or anyone else who might be interested in modeling a 4 square:

Roy Lewallen, W7EL, created a very nice tool called "Arrayfeed1" which can be used to design the feed system for a 4 square.  Use of that tool is described in Chapter 8 of the 21st and later editions of The ARRL Antenna Book.  You can also find an illustrated example in section "Phasing Lines for a 4 Square Array" (fourth bullet) on this page:
