log-periodic antenna

This article is devoted to solving the problem of developing a high-precision radio direction finder for radio emission sources detecting. The paper substantiates the relevance of these devices to date and identifies areas of application. Two versions of the direction finder have been developed - with an operating bandwidth of 100 MHz and a wide-range version with an operating band of about 2000 MHz. Two layouts of these radio direction finders were made, and full-scale tests of individual units of devices and devices as a whole were carried out.
