HA-129 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 and FP Slope potentiometers allow for precise adjustment of these parameters. Additional Gain switch enables the installer to choose the initial gain range. Built-in slope equalizer compensates increased cable loss for higher frequencies (especially important in the case of longer cables). The amplifier has been equipped with 3 connectors: input, output, and test connector (-30 dB).
