Abstract: A reflector sub-assembly for an antenna assembly configured to support FDD and TDD modes of operation is presented. The reflector sub-assembly comprises a reflector defining at least one reflector opening, and at least one first PCB arranged to cover the reflector opening having a first PCB side directed towards the reflector and with a metallic layer thereon and a second PCB side directed away from the reflector and comprising one or more first electric lines. The reflector sub-assembly also comprises an array of first radiators to support a TDD mode extending through the reflector opening and having a feeding end directed towards the first PCB and electrically connected to at least one of the first electric lines and a distant end facing away from the first PCB and carrying at least one first radiating element. The reflector sub-assembly further comprises one or more second radiators to support an FDD mode.

Abstract: A short term, autonomous, electrical power supply system, particularly an emergency short term, autonomous, electrical power supply system. Said system comprises an actuator with an electrical motor (14), an electrical generator (15) for driving said electrical motor (14) of said actuator, a turbine (13) in driving engagement with said electrical generator (15), an generator (7) of combustible, fluidic energy, a fluid line (10) from said generator (7) to said turbine (13), a control unit (5), and an igniter (9) arranged inside said generator (7) and controlled by said control unit (5).
