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 the antenna at a location that has the least amount or no amount of obstructions in the direction of reception.

The Tv/s Must Channel Scan for the Digital 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.
