Radio signal amplifier
If link subject high degree attenuation, the 100 metre radio range insufficient, rendering transmission the radio signals impossible, radio signal
amplifier can installed around half range repeater. All radio telegrams the Radio Bus system are understood, but
only the taught-in ones are amplified. 0. That say, radio signal amplifiers not amplify radio telegrams from other
radio signal amplifiers.
