Planning on getting DirTV with 2 HDTV receivers and the HDTivo and pick up local HD OTA. I am within 10 mi. of the transmitters, all of which broadcast from the same hill. Can you spit roof ant. feed 3 ways and, if so, are there special considerations (i.e., equal lead length?) Would a directional antenna be best in this circumstances? I may have some multipath problems as observed on my rabbit ears/Dish 6000. Ant. recommendations ? Thanks.
