Once we got a look at your TVFool.com page, the problems oyu are having became obvious: you are in a mountainous area, where you are getting signals that are being refracted from mountaintops, and you are subject to severe multipath interference that your MS2000 is powerless to solve.
If you click on the individual stations that are the stations that you are looking for on your TVFool.com report, you will get a graphic representation of the terrain between the transmitters and your house. The graphics indicate real issues with getting a direct signal from any of the local TV stations. Based on the information available, we need to do a couple of things. First of all, we need to replace the MS2000 with a highly directional VHF-UHF antenna that would be mounted as high as you can manage at your location. You have stations that lie in several different directions, an that will require an antenna rotator in order to see them clearly.
If this was my installation, I would use a high-gain, highly directional yagi UHF antenna such as the AntennasDirect XG-91 mounted 4' above a Winegard YA-1713 VHF high-band yagi, which will get the couple of VHF digital stations that are available to you. I would combine the signals from the 2 antennas using a Pico-Macom UVSJ UHF-VHF antenna joiner, and mount the two antennas on top of a Channel Master 9521a antenna rotator. I don't believe that you will need a preamplifier if you are using only one TV set and less than 75" of coaxial cable, but be SURE that the coax cable that you have has NO other equipment connected to if from the new antenna system to the TV tuner. If you use this system, you will have to turn the antenna system using the rotator to see several of your local stations,but you will see all of your local network stations using this installation. I recommend that, when installing the XG-91, that you tilt the front-end of the antenna UP about 20 degrees from the horizon to take advantage of the refraction effects of the surrounding mountains.
