Denny, shown below is the data I took last night. The HD stacker is pointed at 337 degrees since those are the broadcast stations I watch ordinarily (I don't have a rotator).
My HD Stacker is about 40 feet above ground, there is an Antennas Direct CPA19 preamplifier on the pole, and there is a total of about 80 feet of RG 6 coax between the HD Stacker antenna and my HDTV receiver. Please feel free to post my reception figures on your web page. The HD Stacker antenna is a great antenna: especially for people like me that are 60-90 miles from ALL major broadcast towers.
