Well, Comcast has pissed me off for the last time, and I am ready to cut the cable. Most of my electronics knowledge is digital, and I don't know much about antennas, so I am looking for advice. My house is 38 miles from The Sears Tower, and at a relatively high elevation (key word: relatively; this is Illinois we're talking about!). I was hoping to put an antenna in my attic, but I'm not sure if this is feasible. Obviously the roof will block the signal somewhat, but how much would this actually amount to in dB? Would a higher gain antenna make up for the attenuation from the roof? I have quite a lot of room up there, so I could get a huge one if necessary. Any brand recommendations? Thanks in advance.
