we have hundreds of them around us, other than the very obvious path issue potential, there is no RF related issue. When the first major round went in, we were using alvarion baii, which was very dependent on a good ground at the subscriber (you would get zapped on a tower). When they went live we started having alot of issues (ethernet loss, and alot of rf discard) It turned out the highlines in the area were not prepared for the new electrical load, they were overheating, I dont know the mechanics behind it, but they had to do a major project where they went out and tightened the highlines to resolve it, i dont know it this was to shorten them or if tension has some impact at that high a voltage. Once that project was complete the grounding issues went away I just assumed there was alot of shunting to earth and at that scale it impacted the overall ground plane. I could be totally wrong.
