I'm trying to understand why, if they were there to help, they would take out the correct device, the AC7, and replace it with a more lossy, incorrect device, then add an el-cheapo amplifier like a Skywalker (probably a SKY38323). If they used that particular amp and a standard splitter, they probably introduced more than 10 dB of extra noise into the system on channel 49

Did they bring any test gear with them, namely a signal level meter or a spectrum analyzer, so they could actually see and measure the relevant signals before making changes to the system?

Look at the SBR reading for UHF 49 on the DVR diagnostics menu. Between that and the error numbers, corrected and uncorrected, it will give you an idea of what the tuners are experiencing.
