I agree , the big thick dense trees will be a problem for reception with the CM3000A. So install the HD7694P. Start with a aim point with HD7694P antenna at about 290 degree magnetic compass. Here is how to aim antennas ,
http://www.kyes.com/antenna/pointing/pointing.html. THe HD7694P antenna is fairly directional in the forward direction , and will receive at other angles to the antenna and will receive some through the back of the antenna. This is the way that I look up to see what the programing is on tv stations/channels ( this will help in identifying what tv stations are being received and in what direction ) . In the Google search box I type in , as an example , wxyz tv , the two main source of information are wikipedia and rabbitears.info that will show up in the list of web sites as a result of typing , wxyz tv , in the Google search box. Some variations of the search would be , wxyz 41 or wxyz-dt 41.
