A:AnswerHello Mar - Most televisions built after 2007 have the required ATSC digital tuner. You can refer to your TV owners manual for that information.
A:AnswerNo. best bet would be run a splitter with a new coax cable to your other set. You may lose a little signal strength using a splitter but should work ok. Good luck
A:AnswerThe antenna works very well and I believe the cord length is sufficient to place it place it high enough in the room with the tv to pick up signals sufficiently. There is a signal booster that requires power so the location of the antenna needs to be near a wall plug. With digital signals it shouldn’t be necessary to put the antenna in the attic. I put my antenna on the top of the tv cabinet and it picks up quite a few channels with a sharp HD or SD picture.
