This weapon, the Sonic Emitter, is an optional device that you can plant near the center of the ants' home to disable them, though it won't work unless you use either a moderate Science or Speech check. He'll be thrilled that you're willing to help him out, and has a weapon that he's created in order to take care of the problem, just as Raquel said he would.

When you catch up with him, tell him that you've spoken to Raquel about the ant infestation.

He'll either be in his home (marked as Loyal's House), or in the base's humongous hangar. Loyal, like Raquel, can be annoying to find. Should you choose to help her, she'll direct you towards another person at Nellis, an older man named Loyal. You'll learn that there is an ant infestation somewhere within the base that needs to be taken care of. Either way, once you're inside Nellis Air Force Base, seek out Raquel, who is annoyingly difficult to find (though she'll likely be roaming around near the front gate, or perched in her lookout tower). The base is intimately intertwined with the events conducted during the main quest known as Wild Card: Side Bets, so if you need information on how to get to the base itself, you may want to consult the walkthrough. If you're not familiar with Nellis Air Force Base, it's a well-guarded location at the far northeastern reaches of the Mojave Wasteland, where an isolationist group called the Boomers make their home. To undertake this straight-forward side quest, you're going to have to seek out a woman named Raquel, who roams around Nellis Air Force Base. 308 Rounds, 5mm Rounds, 12 Gauge Rounds, 10mm Rounds, 40mm Grenades, 5.56mm Rounds. Nellis Generator Key, Sonic Emitter, Missile (x2), Mini Nuke (x2), 25mm Grenades. (6) Return to Raquel and let her know the generators are running again. (5) (Optional) Activate the sonic emitter. (4) (Optional) Place Loyal's sonic generator on the ant mound. (3) (Optional) Loyal may have something to help with the ants. (1) Restart the 2 array generators, then reset the main power breaker.
