For 1 Tv connected use no splitter.
For 2 Tv's connected use a Channel Master CM3412 distribution amplifier.
For 3 or 4 Tv's connected use a CM3414 distribution amplifier.
The antenna is connected directly to the distribution amplifier and the outputs of the distribution amplifier go out to the Tv's.
Tv antennas like elbow room.
Tv antennas receive the best when nothing is crowding in to reduce or block reception.
Trees and tree leaves do a great job of reducing and blocking reception.
Mount the antenna above the roof where there is the least amount of trees and tree leaves.
Other structures can reduce and block reception.
Mount the antenna at a location where there is the least amount obstructions to reception to the , north west , north , north east , east , south east.
