I live on a corner with heavy traffic in the mornings and evenings (live near a series of schools), which results in RF signal interference (can anyone explain this?). With regular TV it's not a big deal - picture is obviously affected but I don't lose the signal like with digital. The drop outs on HD are a little annoying. Is there anything I can do to boost the signal or make it more stable? I looked a bit into pre-amps but I'm not sure if this is the right route. I just use an indoor bowtie antenna. BTW, when I had a Primestar system the same thing would happen. A loud car would go by and the signal would drop out.
