Where I live, we have like 6 DVB-T MUXes (carriers) in the air, from about 4 directions, with varying signal strength (RX). Years ago when I moved in, I started to look after the "shared terrestrial aerial", serving the small appartment block I live in... I made it through the first retune (analog darkness) and a roof reconstruction with relatively modest investment, and by sheer luck the two bandpass antenna preamps are just about right for the mix of frequencies and levels... Even if we did buy a proper blade chassis with channel cards, the channel amp cards tend to have a limited tuning range = another retune into a different band would cost us another hefty sum...
When the time comes again, I'll see what I can do :-)
Interestingly, as the analog TV channels were squatting in the lower TV bands, the analog phase-out has resulted in most of the DVB-T occupying the upper channels in band V - which I didn't like very much, as the upper channels are a pig to catch if you don't have direct line of sight to the transmitter, and they have shorter reach on the legacy coax cabling I have inherited in the building. Another retune back to the lower channels (in our case, it might correlate with the shift to DVB-T2) might improve signal levels at wall sockets in our house :-) We probably won't be moving back to band III, but even band IV would be nicer to work with, than channel 58 in band V.
