CT-DECT GateCom offers the CT-DECT Multi, a module which is the size of a computer mouse, contains the communication interface unit and a rechargeable battery. It can be clipped on a belt or put inside a pocket of the ground handler and wingmen. Alternatively, radio interface and batteries are built inside the CT-HeavyDuty Headset. The interface to the pilot can be connected directly from the outside to the airplane-intercom. For the aircraft-interface there is a choice between CT-DECT GateCom Compact (in a small soft orange bag), which can handle up to two mobile users at the ground and the CT-DECT GateCom which is a water and dustproof Pelicase, able to handle for example four mobile users on the ground.
