TVFool report for Regina indicates that all of your strong stations on in the Hi-VHF (Ch7-13) Band, which rely on the Rabbit-Ear portion of your Indoor Antenna to receive. Be advised that your current BOTH VERTICAL configuration of the two Rods results in minimal signal output....they cancel each other out. IF any of the stations are broadcasting in either Circular or Elliptical Polarization (both Horizontal and Vertical Polarization are excited), then the Optimal configuration would be at 45-deg.
However, IF ALL are Horizontal Only Polarization, then Optimal configuration would be with both Parallel to the Ground. The Rabbit-Ears would also need to be "pointed" so that the "Beam" of the Antenna is pointed roughly East-West, which means the Tips of the Rabbit-Ears are pointed roughly North-South.
HOWEVER, if you can NOT pickup the Direct Path Signal due to Building/Terrain Blockage, you may find the Best Orientation may be something else....so rotate until you get the best reception.
