I realize IL may be different. But I guarantee that most of the "communication cables" I know of are not 15.5' over traffic. 

We tore one down in our local town a few years back with just a folded field cultivator that was NOT 15' tall. Cable tv company had hung a cable across a street and it drooped. It ripped pretty easily. I coiled it up & threw it alongside a sidewalk. I believe it may have been anchored to houses on either side, or at least one house. Whenever we buy folding equipment, we make sure we try & get the lowest "folded height" possible. Sometimes that means you have to settle for a narrower implement than you'd like for field use.

Electric power companies here do a good job at height clearance. Those "communication cable" (?) companies are the main culprits. The best part is trying to figure out whose cable it is. Someone should know, right? Who? And, is that person accessible by you and I?
