I just bought a 1080p sharp aquos 46 inch at circuit city and it has a QAM tuner built-in. Now what i heard was that you can pick up local hd channels (like our local Fox, CBS, ABC, or NBC), which would be great because i just want their weekly NFL games without the hassle of the NFL package. So I asked teh guy at the store about doing this and extending my range with an antenna and he said "ya you can do that with the optimized for hdtv antennas." So i thought awesome im set. So i bought the Phillips Silver Sensor Digital Amplified Indoor Antenna (PHDTV3) for 50 bucks and plugging it into the cable jack on my new tv. I scanned for all the air and then cable channels. All i got was 3 freakin versions of my local 69 news channel. To say the least i was pretty steamed. One of them was the hd version and it was not even close to hd quality. I guess thats cause i was only getting it at 70%. The antenna is inside my downstairs room. Placement, better ant, different accessory?wat should i do
