Line meter "IL-58".
Instruments for adjusting and controlling the PTA.Since 1958, the "IL-58" line meter has been producing the Slavgorod Radio Equipment Plant. Since 1962, the device was also produced by the Barnaul Radio Plant. The line meter "IL-58" is used to measure the parameters of radio transmission lines. The device was produced in a portable version with power supply from the mains, as well as in a stationary version built into the rack of radio nodes. The last photo shows just such an option. Both factories produced the IL-58 device until 1973.
