Here is Winegard's specs for the HD7696P,

Certainly, try turning the antenna to see if you can split the aim...
If that fails to give acceptable results, a smaller, less directional antenna may work. (HD7694P, HBU-33, etc)
A separate UHF only antenna is an option. (Antennas Direct CS2 or DB2e) You could try a reversed 2-way splitter as a combiner... good luck. If that failed, tinlee.com may be able to sell a tuned filter combiner that adds only one channel to the main antenna down-lead. As I recall, the base model is an AC-7.
