I get excellent reception as long as there's a broadcast within maybe 30 miles or so. When your TV scans it will find different stations with the antenna pointed in different directions. Also, make sure your signal booster is on (light on). When it's off, you're in cable mode. My booster switch is located inside a cabinet under the TV and all three tv connections come from there.
