The 21212 is a 10 ft (3.1 m) roll of 1-in.-wide tape that can help protect the antenna connections in RF, cellular, or satellite networks. After connecting the coaxial cables to the antennas, wrap the tape around the connectors that are exposed to the environment. Only a few inches of tape per connector is required, so one roll will suffice for a fairly large network.
On 17 October 2007, the 21212 replaced the 10413 Cold Shrink Tape, which provided a 1-foot length of tape.
