OK...I have read through the posts and am thoroughly confused...my zip is 22031.  I am using the antenna indoors...outdoors is not an option...on the ground floor.  I cannot pick up any VHF channels..only UHF.  The antennas are 12 miles from my house...I had a clearstream 1...got UHF..no VHF....tried a clearstream 2, and now have hooked up a clearstream 4...still no go.  Do these only get UHF?  
What am I doing wrong?  Specifically trying to get CBS and ABC.  Also..shouldn't my signal be stronger (less breakup/pixelation) on the UHF channels?  Does cloudiness affect this?
Thank you!
Eric
