I'm sure this has been asked 1000's of times. I have a concrete house and my UHF remote for TV2 can't get to my dish box. I have the antenna hooked up fine and the 2nd tv is on a deck outside, funny enough, if I touch the remote to the aluminum frame of the sliding glass door the signal works, but this is funky. How can I boost the signal or reception? Is there an aftermarket antenna that will help or some other solution?
