Nowadays, there is a tendency towards an increase in the number of radio facilities installed and an expansion of the frequency band occupied by them, which causes a growth of mutual interference. In such conditions, it is impossible to deal with disturbances without a comprehensive study of the mechanisms of formation of all types of possible radio interference. This paper is a guideline for improving radio equipment protection against contact interference. The purpose of the study was to improve the contact interference prognostication and influence reduction approach. In the course of the work, we formed a list of factors influencing contact radio interference formation, created a program for contacts impedance and transmission coefficient calculation, specified recommendations for measuring the spectral and energy characteristics of contact interference as well as a methodology for assessing its' levels and defined a list of contact interference reduction measures. We believe that the approach presented in this study can be used while developing radio systems for a specific environment. The paper consists of 72 pages and contains 17 figures, 9 tables and 9 supplements. The list of references includes 11 sources.
