As always trees and tree leaves do a good job of , reflecting , reducing , blocking , Digital Broadcast Tv reception and so do buildings and other obstructions including your own roof and house.
It is best to install the HD7082P antenna at a location that has the least amount to no amount of obstructions of any type or kind in the directions of reception including your own roof and house.
The Tv's Must Channel Scan for the Digital Broadcast Tv stations/channels , often 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.
Go into the Digital Tv Setup Menu and select , 'Air Channels' / 'Antenna Channels'.
