Westfield, Mountainside, Scotch Plains, and Springfield all share the county tower in the mountains. Scotch Plains has been having alot of problems with the tower and looks like they will be upgrading when police department renovations are complete. Mountainside gets alot of interferance on the frequency. The problem with that county tower is just that, in the 70's and 80's there were no towers in the area so dept.s had to use the county tower. It covers Westfield and Springfield the best. Its far from Scotch Plains and Mountainside just gets alot of bad interferance because of scotch plains frequency crosses over sometimes.
