"Unserved household" means your can't get any reception via Antenna, and that D* doesn't provide any locals for your area. You are also required by SHVERA to submit a waiver to the closest affiliates in your area for the networks (FOX, ABC, NBC, CBS) for directv to have the rights to deliver the signal to you. D*'s hands are tied as to whether or not you can get them.
Just remember, if D* provides locals, and you don't already have Distant networks, you will never, ever, under any circumstances, heaven, hell, or inbetween, ever see a DNS on your TV even if God Himself commands it. Will Not happen. D* employees do not (even Access Card agents, and their supervisors) have the ability to add the DNS services to your account if you already have locals.
