    High level output.

    Use imported or high quality domestic module for the positive and reverse channel. Stable and reliable performance.

    Die cast aluminum alloy housing, surface passivation treatment, beautiful and firm, corrosion resistance.

    Waterproof design, strict lightning strike structure, use the rainproof adapter, suitable for outdoor use.

    Internal (or external) positive, reverse input, output. -20dB independent test port.

    Diplex filter, equalizer, attenuator modular, plug-in design, easy to choose or replace for upgrade according to user’s needs at any time.

    Independent installation design for power supply, use 60VAC power supply.

    With AGC control function.
