The bundle offer is intended to appeal to National Football League fans who may be somewhat frustrated by Sling’s relatively limited number of local channels in its lineup. While Sling has deals with NBC and Fox, it’s largely for local stations owned and operated by the networks, which leaves many customers without a local channel option.

There is a catch with Sling’s offer. You have to qualify by inserting your local address here. Sling apparently doesn’t want to include the antenna unless you can get access to your local Fox, NBC or CBS stations with one. (I can’t where I live, for example.)

“Sling TV and over-the-air (OTA) antennas allow you to truly customize your Sling TV service and cut costs, so you can get access to your favorite teams and ensure you never miss a second of the action,” the service says in a press release.
