My antenna setup is a Channel Master 4221HD mounted to a makeshift tower and placed in my family's sunroom. (I originally used a clone which worked pretty well, but the real CM4221HD is even
better!) I also use the Channel Master 7777 Pre-Amplifier. I purchased both the CM4221HD and the 7777 Pre-Amp from the excellent Mississauga based OTA store
Save And Replay. The Pre-Amp
greatly improved my reception, allowing me to receive digital stations I had never seen before. It also helped me solidify my reception on many of the stations I had been having trouble receiving regularly (Buffalo in particular, plus some of the weaker Toronto digitals.) The setup works surprisingly well considering I can't mount the antenna outside of the house at this time.

Below is a shot of the Channel Master 7777 Pre-Amp.

Below is the "hybrid" setup I use now that there are some VHF digital stations that I pick up occasionally. The rabbit ears date back to about 1990 when I was a kid interested in OTA reception and saw that Radio Shack had individual antenna poles for sale. I asked my Dad to help me with the project and he built the antenna for me. Now, nearly 20 years later, those same rabbit ears have helped to pull in digital VHF stations!
