yeah I set my up too but can't get shit because my TV does not have a ATSC tuner
KCBS is a UHF channel. And KCAL 9 is a VHF channel. So you'll need to adjust the two long poles (and make sure they are pulled all the way out) in order to get KCAL.
it's 50$ for a box they locally they raised the price after CBS was shut off
