About a year after my initial installation, I started experiencing signal loss and channels dropping out. So I called The Antenna Men out for a tune up. After a few diagnostic readings, it was determined that I had a defective part. Lance (tech) replaced the part under warranty, rescanned all my TV’s and I now get 40 channels here in Eaton Rapids. Great guys. Great service. Thanks Antenna Men for your great customer service! Highly recommended.
