He said the signal strength is great at the antenna, but it loses strength over the run of the coax. The cm 0747 simply pulls the signal along.
Does that make any sense? If not, some advice on the ideal setup based on my antenna (CS2), location and cable run of 65 feet would be appreciated.

No, it does not. A power supply would have absolutely no effect on the signal and it would make no sense for the installer to put one in your installation unless there is an amplifier somewhere in the feedline. This installer may have placed the preamp at some point other than close to the antenna.
If this antenna system was working fine before, then something has changed.
Sounds like someone needs to physically trace the whole installation from the antenna to the TV set(s) to see what is taking place. There is something awry somewhere. Some possibilities:
Has the direction the antenna is pointed changed? Even a few degrees can make a difference.
A distribution amp or pre-amp somewhere in the line that has gone bad
A defect in the antenna
A loose or corroded connection at the antenna
A loose or bad coaxial connector
A bad splitter (if any)
A bad grounding block
Water ingress/corrosion into any connector
Kinked or damaged coaxial cable
If there is no visible problem then it is a matter of testing or substituting components until you find the actual problem.
If you don't have the knowledge or physical capability to perform such an inspection, then you will probably have to call upon a knowledgeable friend or resort to a professional (preferably one who does not think that a power supply can amplify a signal).
