Without a TV Fool report for the location we are at quite a disadvantage, lacking vital information about your situation.
To answer the question implied by "
Best type of antenna for using with a DVR like a TIVO", The best antenna in one situation may be entirely inappropriate in another.

If there is only one signal that requires a separate antenna, a tuned combiner may be a solution. As you add more signals the cost and complexity of single channel tuned filters quickly becomes less practical.
