SHF filters in spacecraft antenna-feeder systems
The use of SHF-band filters in spacecraft antenna-feeder systems was investigated. These filters, depending on specific applications and requirements, may be constructed both of elements with lumped constants and of elements with distributed parameters.

Checking the parameters of AFS in spacecraft in flight
The use of elements for remote testing of matching of on-board spacecraft antennas, required by the need to receive timely telemetry information on the quality of operation of antenna-feeder systems (AFS) during long flights, is discussed. Information on the traveling wave ratio deficiency to the AFS allowed improvement of quality and reliability of communications with spacecraft and developed telemetric information on the matching of on-board antennas, the efficiency of the feeder system and power of transmitters during long flights.
