Problems solved by technology
[0003] The vehicle-mounted communication device in the prior art can realize the collection of external images and voice signals, and at the same time can send the collected images and voice signals after processing. The biggest difference from the general transceiver station lies in its good maneuverability and flexible Deployment method, but the existing vehicle communication device has a single function and only performs simple collection and transmission, resulting in the collected signal being easily interfered by noise in the complex spectrum environment of the big city, resulting in poor communication effect

Description
technical field [0001] The invention belongs to the technical field of short-wave communication, and in particular relates to a vehicle-mounted short-wave communication device. Background technique [0002] The short-wave communication system is composed of a transmitter, receiver, antenna system and various terminal equipment. Since long-distance communication or broadcasting requires strong transmission power, and the receiving system needs to be far away from interference sources, the transceiver station should generally be set In the suburbs, for large cities with many stations, it is necessary to plan and set up the sending area and receiving area, so as to avoid the high-sensitivity receiver from being unable to work due to the strong transmitting power. Generally, there should be a clearance area of several hundred meters in front of the short-wave transceiver antenna, and there should be no tall trees or buildings, so as not to block the radio waves, and there shou...
