For the Reception of Tv Transmissions.
-->As Always<-->Attics and the Inside of Buildings Are Not a Reception Friendly Environment , and Never Will Be a Reception Friendly Environment.
For reception of the Strong Signal Strength Local Digital Broadcast Tv Stations/Channels.
Yes start with a ,

HBU33 antenna , in the attic , aimed at about 40 degree magnetic compass direction.
--------------------
Here is how to aim antennas ,

If reception situations happen in the attic that are not resolvable with antenna aim adjustments and antenna location adjustments in the attic.
Then move the HBU33 antenna to above the peak of the roof in such a manner that reception is not , obstructed , impeded , blocked , by the , attic , roof and building in the directions of reception.
The directions of reception at your location are , East , North East , North , South South East.
The HBU33 antenna above the roof can be aimed at about 40 degree magnetic compass for reception of the local strong signal strength Tv stations.
--------------------
As a Test of reception for more Tv stations channels , with the HBU33 antenna above the peak of the roof.
Can aim the HBU33 antenna at about 180 degree magnetic compass direction to receive weaker signal strength Tv stations to the South South East.
And the stronger signal strength local Tv stations will be received at back angles and back of the HBU33 antenna.
