For 1 Tv connected use no splitter.
For 2 tv's connected use a common simple 2 way splitter.
As always , trees and tree leaves do a real fine job of reducing or blocking Tv reception and so do buildings and other obstructions.
It is best to install a antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception.
At your location that is , north , west , south west , north east.
The Tv/s Must Channel Scan for the Broadcast Tv Channels , sometimes named the 'Air Channels' or 'Antenna Channels' in the Tv setup menu because the Tv transmissions travel through the air from the transmitting antenna to the receiving antenna.
DO NOT channel scan for cable tv channels.
