HA-129R65 amplifier can be successfully used both in small private installations as well as in medium-sized MATV systems. Its elegant and modern-looking housing contains RF amplifier and power supply. FP Gain, FP Slope, and RP Gain potentiometers allow for precise adjustment of these parameters. Additional Gain switch enables the installer to choose the initial range of forward path gain. Built-in slope equalizer compensates increased cable loss for larger frequencies (especially important in the case of longer cables). The amplifier has been equipped with 3 connectors: input, output, and bidirectional (also for return signal) test connector (-30 dB). A new feature is active return path.
