Experiment with antenna height and aiming, because a few inches can make a big difference. Have someone watch the set and report of reception quality as the antenna position is changed. Keep lead-in line free of splices and sharp bends. Form the lead-in line into a half loop where it enters the house, so rainwater will drip off. Seal the entry with a waterproof material.
Most splitters weaken signals.
If signals are weak a splitter and an amplifier or distribution amplifier may be needed. UHF stations are usually transmitted either on an unused VHF channel or on one of the special cable channels available through a set-top converter furnished to the subscriber. The cable company will provide a listing of channels to which the UHF channels have been converted. On newer television sets, the setup menus allow for either off air reception or cable reception. Make sure that you chose the appropriate setting for your situation Currently KDAF WB33 is not available on any of the satellite services.
