OK, I purchased a Samsung SIR-T150 today, a RS double bowtie and an inline amplifier. Absolutely no signal indoors. I am surrounded by some rather tall buildings. I have a small north facing balcony on 26th Street on the west side of Manhattan, so I put the antenna outdoors. I am getting CBS, NBC, UPN, WB and PBS, but I have to move the antenna around to get these signals. No luck on ABC or FOX. Would a larger outdoor antenna help? If so, what model is recommended? Can't be too big as my balcony is small. Thanks.
