It could be any of the places/causes you cite. You need a good signal strength meter (or a tech with one) to plug into the line at each of the transition points to see what kind of signal you are getting in the DTV band. I don't know what the frequency band is for DTV, but be sure that the in-line amplifier you are using is rated for the frequency band of interest. The old one may not be. The same is true for the coaxial cable that you are using. If DTV is at a much higher frequency than the analog signals you were using, then the existing cable will be much more lossy at the higher frequencies, and you will need new "low-loss" coax cable.
Even the antenna needs to be one that is tuned to the DTV frequency band. The old antenna may not do a good job. I don't have any interest in over-the-air DTV; analog Cox cable is ok for me, so I don't know the specific frequency bands that are relevant. Used to know all the frequencies when I was a kid, but I've forgotten them all, and they have all changed anyway.
