Home Products Amplifier Intermediate amplifier
Intermediate amplifier

The intermediate amplifier is designed to amplification the signals of GLONASS and GPS satellite ranges L1/L2 with the antenna unit. The amplifier is also performs transit of signals RTCM and power voltage. It is used to compensate for the attenuation in the RF cables.
