So I am cutting the cable on a couple of our TV's to save some cash. Unfortunately, given that we live in CR where the local broadcasts actually originate from 30 miles northwest of town and we live on the southeast side of a ridge, indoor antennas don't seem to be cutting it. I am thinking the best option will be an on roof antenna that I can plug into our existing Directv splitter. Does anyone have any experience with this? I'd love some direction on which antenna to buy and installation.
