There are a few UHF only designs that happen to have some useful VHF capability and vise versa. However, if you really need VHF performance, you need to use an antenna that was intentionally designed for that frequency range.

The problem I've observed when receiving VHF through a UHF only antenna is the signal quality (not to be confused with signal strength). Two factors appear to play a major role in this, widely variable frequency response outside the designed operating frequency range of the antenna, and unacceptably high VSWR (voltage standing wave ratio). Both factors are closely related and contribute to the signal being distorted before it is delivered to the tuner.
If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)
