The DB8E is a great UHF only design. (Real CH-14 through 51). It does not have intentional support for the reception of real channels 13 and lower.
You can combine a UHF only antenna with the output of a VHF only antenna using a filter network, commonly called a UHF/VHF combiner. Example:

The DB8E would connect to the UHF port, the Y10713 would connect to the VHF port and the output would feed the TV or splitter.
