Brief Introduction:
Two-way user amplifier uses push - pull module to enlarge forward, built-in branch allocation selection output. The low-frequency channel is reserved to provide electrical length control. Applicable to cable TV and data two-way network.
The installation for outdoor use, this machine can be directly overhead on the cables installed, also can be installed in the rain or in the indoor, require good grounding, grounding resistance Ω 4 or less.
Each port can be connected with a waterproof joint or the through head is directly pressed with the terminal post.
