NAXA Amplified Outdoor HDTV Antenna With Built-in Rotator (NAA-351)

My first antenna was an indoor $20 piece from Walmart. Great re-introduction to antenna tv, but only a dozen channels. Had it for a week before this one arrived and gave me over 60 channels sitting on the back of the recliner. Over time, the number of channels has decreased. I get a half dozen Spanish channels, a half dozen shopping channels, a half dozen church channels, a dozen or so pbs channels (but Ive lost a half dozen from the north). All the major networks from Philly, but nothing anymore from WilkesBarre Scranton, and never anything from NJ/NY. Not sure how I lost the channels without moving the antenna. Anyway, it serves me well, but ultra-lightweight metal construction with plastic connectors. I might get around to trying it in the attic, but it's way too fragile for our wind or tonight's blizzard. For now, super reception just sitting on the back of the living room recliner. My next antenna will be higher (in the attic) and larger to see if I can get more channels, but I don't want to spend over a hundred bucks for just a half dozen pbs and shopping channels. Maybe I'm shooting for the moon, but Harrisburg to the west and NYC to the east are only about a hundred miles. This is my starter antenna, and it has served me well. Can I join two or three directional antennas pointed in different directions? I'm off to YouTube.
