Going by this picture,
Antenna, the short stubby antenna elements should be aligned at a right angle to the TV transmitting antenna.
Put another way, you'll be pointing the end of the structure that's supporting those short antenna segments (that are parallel to the main wings) towards the transmitting tower.
Usually, towns and cities have all the transmitters for different TV networks all on the same or nearby hills so generally if you're within 25 miles of the towers you only need to point in one direction. I do have to occasionally turn the antenna to improve the signal for a certain network. Where I am in Sioux Falls, I don't even get ABC. Note that TREES play havoc with TV signals (and Wifi signals).
