Just a comment. I think I said before that my suggestion would be replace it with a Winegard Sensar IV..
Well after over 14.5 years I did it. . Forgot to put the antenna down when changing campgrounds.. so got to where I am today and it was Gone gone gone
So I did a quick google search and less than 50 dollars later a new Sensar IV head was in the park office when I went to do laundry today, I'd picked up a new connector Sunday so when I got back from the laundry (attached to park office) I broke out the telescoping ladder and went up and re-dressed the cable and compressed on the connector.. Then down and back up with the new head. Then down and crank it up and aim it.. Signal strength way better than I have ever seeen (two stations hit 98 on the TV's signal meter) one station I'd not seen before (4 services) Oh yes.. The old Wingman had a broken wing (this fixed it) and the antenna drooped a bit (This one does not) and it is a 4 not a 3 so it's an serious upgrade.
Happy TV watcher I am once again.
I repeat Replace that omni Piece of Junk with a Sensar IV.
