[TowerTalk] Parasitic 4-square for 40 meters

[ABowenN4OO]

I assume that you are speaking of a vertical parasitic array which will 
cover 4 directions.

You will find a discussion of such arrays and the requirements for proper 
operation in ON4UN's, Low Band DXing, Chapter 13, paragraph 3.9. Note that 
the ground radial requirements are quite stringent, which may explain why 
most operators opt for current forced, driven arrays.

Driven arrays are covered in chapter 11 of the same book.
