This is in the DISH Playmaker owner's manual:

NOTE A 25 foot coaxial cable is included and recommended for use with the antenna. Longer coax runs could potentially cause intermittent problems. Maximum cable length should never exceed 50 feet.

Maybe it doesn't really matter, maybe they are concerned about OSHA trip hazards, maybe ours is an old system and the new systems are different? Whatever, this is what Winegard says....
