Is there a reason they don't mess with UHF? Studying for my ham exam as we speak.

Because they don't operate in the UHF bands' frequencies. https://en.wikipedia.org/wiki/Broadband_over_power_lines#Imp... says "0-30MHZ" (that's the HF bands) "and sometimes as high as 80Mhz" (50Mhz would be 6-meters)

UHF does not propagate through power lines, the frequency is too high.
