  1. I have this antenna on my old house, and it does a great job. I just moved 60 miles away and all the houses including the one to which I moved have this same antenna. All the major channels come in perfectly.

  2. The 4228 is made in China so quality is poor compared to USA made Winegards

    So unless all your stations are UHF and in the exact same direction, you will need to buy a different antenna or a expensive rotor
