Another Progressive HW-50 tale. Three weeks ago while we were camp hosting @ Cumberland Mtn. State Park in Crossville, Tn., there was one lightning strike that hit the campground during a storm. It struck two trees about 80' from our camper, dug a ditch through the ground about 30' to our satellite coax, then into the camper. It took out our TV, satellite coax,satellite box, 3 led lights,the converter, and my EMS. Needless to say, our hosting job ended two weeks prematurely. The mechanics in the shop think that the Progressive unit probably saved the camper. JT
