I had a Terk TV55 some years ago. It was an overpriced piece of junk.
Adding a cheap amplifier to a simple dipole is not the best way to make a quality antenna.
If you would like, you can post your TV Fool results for your reception location and get some recommendations for an appropriate TV antenna that will work better and cost less than the TV55.
