Once again I have called in favors from the best people in the business to help me verify and check the additional chapters in this second edition.
In particular I want to thank my friends and colleagues for many years for their input and help on the repeater and tunnel planning section; Mr Henrik Fredskild — Denmark, and Mr Stephen Page — Australia. Your input and guidance has added enormous value to the new chapters in this second edition.
I also want to thank: Mr Lance Uyehara — USA, Mr Jaime Espinoza — Chile, Mrs Marianne Riise Holst — Denmark/Norway, Lars Petersen — Spain/Denmark for their input and corrections.
Also, thanks to so many of you who have given me so much positive feedback, via mail, via groups on the WEB and at conferences and meetings, etc.
When I was writing the first edition I was not sure that there was a need for a book covering the practical approach — now I know.
Thanks once again to the team from Wiley: Mark Hammond, Susan Barclay and their team, for their support in the production of this book.
Last, but not least, thank you Karin, my dear wife, once again for your patience — even though I did promise you not to take on yet another book. Thanks for your support on this project, and for once again letting me spend so many late nights, early mornings and weekends on this book.
Without your support and patience Karin, this book would not have been possible.
