During the summer I went up onto my roof and installed a R Shack UHF onl Ant with a 8ft mount and I still could only get cbs from the ESB at around 55. Problem was , my sig would be 55...then 40...21...0...55....32....and so on. I live in SI, NY and from my house in the direction of the ESB there is a HUGE tree. I gave up during the summer and decided to wait for TWC to offer their HD package which I had installed last Sat. I watched ABC and NBC's HD programming for the first time tonight and I loved it. Since TWC has yet to turn on CBS ....I tried again with a Radio shack B Tie ANt. Andsince that big tree has no leaves now, I get a sig of around 60-65 without dropouts. Long live hd!!!!
