My friend who was (recently passed) a telecommunications engineer made one of those "clothes hanger" antennae and stuck it on the side of his house -- not even high up. Worked a charm. And they're a good 25 - 30 miles from most of the broadcast locations.
He sent me a YouTube link to instructions for one. Not hard to do.
Of course, results vary. But perhaps worth looking into.
I just stuck one end of about 3 feet of hookup wire into the antenna port on my TV and it worked fine. I made one of those HDMI antennas from instructions off the internet, and it only works marginally better.
The interesting thing is I could pick up channels over the air that were not on the cable TV lineup.
