To improve her chances of better NBC reception, I suggest the 91XG with the front tilted up 5 to 10 degrees by trial-and-error testing, aimed at 323 degrees magnetic, and a Channel Master 7777 preamp. The antenna must be mounted in a location that does not block the signal with trees.

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.
