<p>A portable Ku.c.s waveband satellite ground receiving and emitting device, which comprises a dish antenna, a Ku.c.s multipurpose high frequency adapter, a Ku.c.s multipurpose transmitter, a Ku.c.s multipurpose receiver, LCD display and power unit, characterised in that the dish antenna consists of a inflated body, the body is fixed inside the upper and lower part of the cabinets of the device with hinges, the front face of the body imparts a shape of paraboloid when the inflated body is released and is covered with a layer of conductive metal, and a support for the antenna feed assembly is located in the center of the body. The outer end of the support is used to hold the antenna feed assembly, and the inner end is versatily joined with the fixed seat on the body through a main bearing. The inflated body has a gasbag structure connected to a mini-inflating pump through gas circuit pipeline. The power source of feeder is focused manually or automatically, in order to meet the requirement of receiving and emitting different wavebands. The use of satellite ground receiving and emitting device is made more extensive and convenient. <IMAGE></p> |
