Return channel amplifiers ARM

31 nominal dollars

* It is intended for retrofittable CATV networks containing amplifying equipment with a passive reverse channel or without it
* Modifications with a reverse channel range from 12 to 30...65 MHz to raise reverse channel noise protection from man-made interference
* Output level control
* Built-in test output
* Built-in power supply device
* Screened and protective case
* F-type connectors
