Sometimes my reception is "iffy." This may sound like a stupid question, but, how on earth would I attach an outdoor antenna to my bricks? And how do I know where to put it since it would be permanent? Can you use that putty I see advertised on TV? I have a very large tree out front that may be blocking my reception during the summer as it produces millions of leaves. Right now my reception is best if I keep my antenna inside, but there are times when absolutely no bars are showing on my receiver. HELP!! Thanks a million!
