There are no low band repeaters per-se. There ARE low band remote base stations around controlled mostly on UHF, and most if not all are owned privately since you as the operator on UHF are a control operator for the remote transmitter.You obviously also need to possess the class license of the transmitter you control even though you are coming in on UHF (tech and above). There are exceptions tho.
There are a very few repeaters down as low as 6 Meters around the country as well, but the majority are VHF/220/UHF
