I don't know where I got that from now. It must have been related to reading 60+ pages of that report that day. Must have read into something dealing with MPE that wasn't really there.
For those of you interested in reading it, the only important parts, really, are pages 100 - 112... and not all of those are of particular concern to the operator. I believe they are referencing obstructions in that statement, such as terrain, buildings, etc. It is impossible to have an antenna of 0 dBi, and that is the only antenna that will receive signals equally in all directions. They even require a 6 dB antenna minimum, which varies drastically with each antenna model as to it's radiation pattern. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------- From: "John Valenti" <[EMAIL PROTECTED]> Sent: Wednesday, November 19, 2008 6:20 PM To: "WISPA General List" <wireless@wispa.org> Subject: Re: [WISPA] TVBD height requirement > Mike, > > Where are you reading this on page 43? > > And I've made it farther back in the report... > > Is Appendix B (Final Rules) the actual rule?
