The above document was written by Alfred T Yerger II on January 10, 2010 and wanted to share it here for those of us who work on and at sites on a fairly regular basis as well as for those looking to build something new at an existing or new site. This document really was written with regards to there being seen a slight degradation is receive sensitivity after migrating to narrowband. I myself have not seen this in my personal experience, but this may be due to the original system design. But now also have some additional info and data to do a more detailed look at things with the pending addition of new equipment on the horizon if things go as planned.
