Terry,
Maybe I am confused.
But isnt there also going to be some spectrum re-capture of some TV channels for other RF uses?

Can youu clarify what VHF channels are being refarmed for other uses?  Or is it UHF< or what?

thanks

Bob, WB4APR

So I am cutting a hole in the bottom of the bay, where the TV can disappear down into the lean-to roof attic of the first floor below the window.  This and 60 lbs worth of springs and mechanism to make it easy to pull up and down.
