I'm not familiar with your model, so I can only make some guesses. You did not indicate if your neighbors were having the same reception problem, so if you haven't already, I would check to see if you just happen to be out of range. Since you have a 2012 model, your's should be a digital antenna.
I'm not sure it would help, but you can purchase an antenna booster from less than $20.00 to more than $50.00 (Google TV antenna signal amplifiers). You install it onto the coax between the antenna and the TV. It has a power pack that you plug into an electric socket to power it.
On my 2003, the original bat wing antenna was not digital and had no booster. I have to say that when I tried adding a signal amplifier, I had little success. I bought it at Radio Shack and returned it the same day for a refund. I changed the antenna to a digital one last winter and went from 2 stations to 15. The new one cost less than $60 and came with a power booster.
