Abstract
Description
Technical Field
[0001] The utility model discloses a fixture for losslessly installing an antenna of a portable communication radio station used on a helicopter, belongs to the field of wireless communication, and relates to a structural fastening technology. Background Art
[0002] Since the helicopter is made of a metal frame and metal skin, when a portable communication radio (antenna is directly fastened to the radio) communicates with the ground in the helicopter, the radio is large and needs to exchange data with personnel or equipment. Therefore, the radio (and the antenna on the radio) cannot be placed directly against non-metallic glass, resulting in most of the wireless radio frequency signals being shielded by the aircraft skin, thereby affecting the ground communication distance. If the radio is left in the cabin and the antenna is fixed outside the cabin through an RF feeder, the communication effect will be greatly improved. However, this work involves the modification of the aircraft (opening a wire hole in the fuselage and installing a fixed antenna structure outside the fuselage). There are strict requirements for aircraft modification in my country and internationally. The modification of the aircraft requires professional institutions to conduct design simulations and organize meeting reviews, and then obtain an airworthiness certificate after multiple flight tests. This work is technically difficult, has a long cycle, and is costly.
[0003] The utility model discloses a fixture for losslessly installing an antenna for a portable communication radio station when used on a helicopter, which can realize lossless installation of the antenna on the glass inside the cabin during the application of the portable communication radio station on the helicopter, thereby minimizing the shielding of the aircraft skin on the radio signal, and at the same time, there is no need to modify the aircraft, the cost is low, the communication effect is good, and the utility model has high practicality.
