Mine has been in use for 5 years and never a problem. I added 80 mts and works well. 60 feet of electric fence wire under top hat screw and tied off about 6 feet off the ground and works well and helped receive on the other bands. A easy fix and works like it should. For the cost of the add on about $3.50 It is now the cheapest 10-80 vertical out there and works GREAT. 73 Jim
