Hello, tally:
I think you should stick with the NE stations; the ones from the SW aren't major networks. If you go here and click on the callsigns you can see the networks:

An "Omni-directional" antenna is a description used by marketing departments that gives you false hope. For best results the antenna should be aimed at the transmitter.
It is possible to aim the antenna SW for the weaker signals and receive the strong signals off the back IF there are no trees or buildings in the signal paths.
As an alternative, you could remove the reflector screen from an Antennas Direct C2V to make the antenna bi-directional.
But, I still favor aiming an unmodified C2V or RCA ANT751 to 55 degrees magnetic. No preamp is needed with your very strong signals. They are so strong that they might overload your tuner.
The only odd channel is ION which you have a good chance of picking up from the side of the C2V.
How long will the coax run be from the antenna to the TV? How many TVs are you using?
With signals that strong, an attic installation might work.

If the antenna is outside, the coax shield should be grounded with a grounding block that is connected to the house electrical system ground with 10 gauge copper wire for electrical safety and to reject interference. For further compliance with the electrical code (NEC), the mast should also be grounded in a similar manner to drain any buildup of static charge, but the system will not survive a direct strike.
