An air tank for a self-contained breathing apparatus that incorporates a coil antenna for use in a magneto-inductive system. The coil antenna is formed as a part of the tank. The antenna is embedded within the sidewall of the air cylinder to form the air tank. The self-contained breathing apparatus may include a magneto-inductive device operatively connected to the coil antenna for conducting magneto-inductive communications. A microphone and speaker or headset may be included to facilitate voice communications over the magneto-inductive system.
