It sounds like you only need to request the coupons if you use any kind of antenna to get TV channels.
If you have satellite or cable TV for all of your TVs you should be OK.
your provider will provide it if anything is needed.
[The first 22 million coupons will go to all households that request them. That
includes a residence that gets cable service for one television but has a spare TV that still uses an antenna, for example.
The rest of the coupons, however, are meant only for those who do not subscribe to a pay-television service.
The Nielsen Co. estimates that 14.3 million households, or about 13 percent of the 112.8 million total television households in the nation, rely on
over-the-air television broadcasts for programming.]
