FE 3 block lifts

Also, this device can be called: FE3, FE-3.

FE 3 block lifts complete with dipole type DP-1, the log-periodic antenna type LPA 1 and antenna support structure of ATR 2 is used to measure the field strength of the measuring set-type FSM 8 and provides continuous height adjustment and antenna polarization.

FE 3 product (with the dipole pipe) in combination with DP 1 and ATR 2 is designed to control the interference field strength; useful measurement of field strength.

Also product FE 3 is combined with LPA 1 and ATR 2 and is used to measure the field strength at the transmitter, the study of propagation conditions for the design of transmission systems, and establishing limits for unwanted emissions, control of the radio.

Specifications FE 3:
