Abstract

In the report transfer factor for some types of short wave antennas are displayed. They guarantee the optimum matching of a preselector with an aerial on average frequency, and allowing to establish of preselector frequent properties. With the use of (3), (4) the influence of matching devices accuracy on the quality of the reciever was analysed. It was provided, that by use of a preselector with a quality factor 104 and a structure with traditional types of a short wave range antenna, the tolerance of all the elements used in a matching device makes about several percents. The increase of the resonator quality requires the increase of the matching accuracy above which grows proportionally to resonator quality.
