A Simple reception situation.
Above the high point of the roof in such a manner that the roof and house are not blocking reception to the , south east , north east.
Install a Winegard HD7000R antenna aimed at about 31 degree magnetic compass direction.
Here is how to aim antennas ,

The HD7000R antenna has some forward antenna gain for the Weaker Signal Strength Digital Broadcast Tv stations/channels to the , north east.
And being a small directional antenna , it is not all that directional and will also receive the Much Stronger Signal Strength Digital Tv stations/channels to the , south east , due to the fact that directional antennas also receive to a lesser degree to the front angles , back angles and back of a directional tv antenna.
The least amount of reception at a directional Tv antenna is directly on the sides of the antenna.

A preamplifier is not required.
_____________________________
For 1 Tv connection use No splitter.
For 2 Tv's connected use a simple common 2 way splitter.
For 3 or 4 Tv's connected use a , Channel Master CM3414 distribution amplifier.

Here are some above the roof antenna mounts.

For a FM antenna above the roof , I recommend a Antenna Craft , FMSS , antenna.
The FMSS is omni directional type antenna that will receive the local FM radio stations.
For the best Quality FM and Tv reception , I recommend have a Separate coax for the FMSS Antenna that is not connected to the Digital Tv system coaxes.
The local FM radio stations are strong signal strength , No requirement for a amplifier with the FMSS antenna reception
________________________________________
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 antennas 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.
________________________________
Separate the HD7000R antenna and FMSS antenna by about 3 feet on the same mast. The FMSS antenna above the HD7000R antenna.

The Tv's Must Channel Scan for the Digital Broadcast Tv 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.
Some Digital Tv's will automatic channel scan for cable tv channels.
DO NOT channel scan for cable tv channels.
Go into the Tv setup menu and select , 'Air Channels' / 'Antenna Channels'.
