Would you recommend sticking with the antenna I have and getting a "pre-amp" ?
I think you should make some tests with your present antenna to see what it will do, and then upgrade based on the results of the tests.

First aim your C2V loops at K26DD just to see if your system is working. Then aim the UHF loops at 119 for K24ID NBC and the "V" dipole broadside (perpendicular to) at 191 for KCFW NBC. If the signals are too weak add an Antennas Direct Juice preamp and and perhaps an FM filter (if needed) because you have a strong FM transmitter that might interfere with the reception of real channel 9.

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 which will tend to discourage a strike, but the system will not survive a direct strike.
