Antenna site interference is a problem that has plagued the Land Mobile Radio communications business since the inception of two-way radio. There are techniques for operating a clean antenna site so that each radio operates with little to no interference from each other at the site. When properly implemented, these techniques can also reduce or eliminate interference from other radio sites.
