An emergency indoor television antenna is inserted between a cable television wall outlet and a television set that includes a coaxial cable connector. The antenna comprises a spacer containing an electrical conductor that connects to the central conductor of the coaxial cable connector of the television set on one end and to the shielding of the coaxial cable connected to the wall outlet for the television set on the other end. Optionally a switch may be included selectively to connect the electrical conductor to the shielding or to the central conductor of the coaxial cable.
