Theoretically, an antenna with a gain of 22 db and a preamp with a noise figure of 2 db; preamp gain of 23 db or more, and coax plus splitter losses of 6 db or less. This calculation allows for a receiver noise figure of up to 7 db.

Such antennas are impractical, but if you can eek out 6 db of ground gain it's not as bad. Even then, expect frequent dropouts.
