Buy an amplifier for the antenna to get the most out of it. I was able to triple the number of digital stations I could pull in. Install it right at the antenna if you decide to split the signal to different TVs.
I don’t think your experience is that typical because of s/n issues in most metro areas but I’m glad it worked for you.
You say triple the number of stations but how many networks.....ABC, CBS, Fox NBC and PBS....... what else?
