Re: [TenTec] OT: Lightning and Grounds

Good but I feel it's important to keep the antenna at ground potential. I 
found this out the hard way once when lightning actually hit the cf zepp 
directly. It came down the feeder then jumped 10 feet to the nearest 
electrical outlet destroying nearly everything electrical in the house. The 
zepp and feeder evaporated leaving small shreds of insulation around the 
yard!
