Also, in your opinion, do you think the cost would justify taking a chance of maybe being able to get reception?

Glad to hear you are willing to experiment.
If cost is not a factor, I suggest a Winegard HD7698P antenna, an Antennas Direct Juice preamp, a Yaesu G450A heavy duty rotator, and an Antennas Direct FM filter if needed. If your TV is not able to add a channel after scan, you will need to rescan after each change of direction. If more than one TV is being used, someone has to decide which direction for the antenna.
If cost is a factor, I suggest you try one inexpensive fixed antenna to see what you can get. First try a Solid Signal HDB91X UHF antenna aimed at 356 degrees magnetic for KMPH Fox. If the signal is too weak, add an RCA TVPRAMP1R preamp.
Next aim the antenna at 138 degrees magnetic to see if you can receive KBAK CBS.
Then, aim it at 329 degrees magnetic to see if you are able to receive KSEE NBC. That antenna has a tilt feature; sometimes it helps to tilt the front end up (maybe 10 to 15 degrees) to catch signals coming down from a peak.
Then add an MCM 30-2476 VHF antenna aimed at 138 degrees magnetic for KERO ABC. The RCA preamp has separate VHF and UHF inputs for the two antennas; move the switch to separate. If the switch becomes erratic, set it back to combined and use a UVSJ before the preamp to combine the two antennas.
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.
