Couldn't agree more. Excellent coverage in this book, plus recent editions include a ton of software that will help you design the system, especially the phasing lines or phasing networks.
As with any vertical system, the radial field will make or break the performance.
If the verticals are short then its possible to use 1/8 wave spacing but in all cases I suggest you get ON4UN's Low Band DXing book, 5th Edition on line or at ham stores.
