description FIELD: radio electronics; floating means design. ^ SUBSTANCE: proposed symmetrical-input antenna amplifier incorporating provision for matching feeder with signal source and with output wave impedance at minimal distortions in 0.1 to 10 Hz range and gain factor of at least 40 dB has low-noise input amplifier built around two transistor input stages 1, 2 connected in common-emitter circuit; differential amplifier 3; voltage follower 4; and output power amplifier. Transistor stages 1, 2 are loaded into differential amplifier 3 built around two intercoupled operational amplifiers; voltage follower 4 is connected at input of power amplifier and loaded into two amplifying channels of output power amplifier with inverting and noninverting operational amplifiers 5, 6 whose inputs are connected in parallel; these operational amplifiers are loaded into identical current amplifiers 7 built around push-pull emitter followers with two complementary transistor pairs. ^ EFFECT: reduced distortions in extremely low frequency range. ^ 1 cl, 1 dwg
