FIELD: radio-technical information systems using elements designed for other purposes, unrelated to informational purposes.
SUBSTANCE: radio-technical information system contains at least one passive repeater mounted on air power line support, and power supply of ground-based radio-technical equipment is connected primarily to power lines through energy takeoff device. Passive repeater is also functionally connected to ground-based radio-technological equipment located near it and containing an active repeater. At intermediate repeating stations pairs of passive repeaters are located primarily on neighboring air power line supports.
EFFECT: realization of information support without substantial investments into construction of masts due to usage of air power lines, usage of same air power line as electric supply, increased reliability of radio-technical information system, decreased operation costs.
