Query: Didn't work as expected

I bought this antenna after researching zones online. This item was rated for all the zones I needed and I thought I would be able to pick up a minimum of five or six digital stations. I ended up with two analog and two digital. What I failed to factor in was the signal strength stations were using to transmit their signals. Even though this antenna was appropriate for zones and distances to transmission towers, it seems like it is not adequate based on signal strength. If I had better signal strength, I may have been able to give it a higher rating.
