You won't get a waiver if Directv is providing locals to you and you simply don't want those. Doesn't matter if you can get them OTA or not. If Directv does not provide locals to you just because you can't get them OTA alone is not enough if a Waiver is not granted. You have to find out if with a better antenna etc you could. There is a process to qualify you that you can not actually get OTA and what networks you can't get.
In addition, you can NOT ask for a waiver on your own that is not correct information. It has to go through your Satellite provider. You stated Directv does have your locals so that is why Directv is probably not submitting a waiver, and they are under no law that make them in any case.
"6. How do I know if my household is “unserved” with respect to over-the-air television broadcast stations?
All full power television broadcast stations are required to transmit their signals in digital format. The FCC has created a computer model for satellite companies and television stations to use to predict whether a household is served or unserved with respect to digital signals. The satellite company, distributor or retailer from whom you obtained your satellite system and programming should be able to tell whether the model predicts that you are “served” or “unserved.” The FCC does not provide these predictions.
If your household is predicted “served,” you are not eligible for distant stations unless the station predicted to serve you grants you a waiver. You must ask your satellite company to request a waiver from the television station on your behalf. The station has 30 days from the date it receives the request to either grant or deny it. If the station does not respond within 30 days, the waiver is considered granted and the satellite company can provide the distant signal. However, the satellite company is not required to provide distant signals and may decline to do so or may choose to wait longer than 30 days before doing so.
If the station denies the waiver, you can request a signal strength test be performed at your home to determine whether the TV station’s signal meets the FCC’s signal intensity standard for digital signals. Although the satellite carrier is not required to act on your request, if the carrier does accept it, the test should be performed within 30 days after the date it was submitted. The test must be performed by an independent tester selected by the satellite carrier and the TV station. If the satellite carrier requests the test and the station’s signal exceeds the signal intensity standard, the satellite carrier pays for the test. If the station’s signal does not exceed the signal intensity standard, the station pays for the test. If the satellite carrier does not act on your request and you reside in a DMA where the carrier does not offer local-into-local service, you can arrange for the test yourself. You will have to pay for the test no matter what it shows and the price may include the cost for the tester to come to your home. The test must still be conducted by an independent tester that both the network station and the satellite carrier have approved. If a satellite company and the TV station are unable to agree on someone to conduct the test, the FCC has designated the American Radio Relay League (“ARRL”) as the independent and neutral entity to approve the proposed tester."
