Here is how to aim antennas ,

The front of a antenna is aimed at the Tv stations.
Aim the antenna at about 310 degree magnetic compass.
Also the antenna has been exposed to the weather for a long time. If you intended to try and use the beat up antenna.
Replace the matching transformer (balun) with a NEW matching transformer (balun).
Replace the coax with NEW RG-6 coax.
Check all other coax connections and hardware.
If you will like to bypass the issues that will be with the old beat up equipment.
Then install a Winegard HD7000R antenna aimed at about 310 degree magnetic compass.
Also replace the old coax with NEW RG-6 coax and coax coupling hardware like ground blocks and splitters and etc.
And speaking of splitters , How many Tv's are/will be connected??
