I had a narrow escape using The Unger alloy pole. My village is cursed with overhead power lines, some as low as 10 ft. I was cleaning in light drizzle one day when I touched one. Luckily, I was wearing rubber gloves. The contact made a sharp crack, and burned a hole in my angle adapter. These lines have been up for over 40 years, I guess the insulation has eroded in places.
Take care, Dai
