Adjusting illustration

A  Proper adjustment of the antenna's position so that the best communication quality and signal strength.

B  Indoor antenna installed location should stay away from one end of the outdoor antenna, so as not to interfere with each other. (The outdoor antenna away from the indoor antenna placed above a layer of floor is better)

C  Indoor antenna should be installed above the height of 2 m of the ceiling or the corner.

D  Using the waterproof tape to wrap where has connector, so as to avoid oxidation caused by moisture, resulting in reduced indoor signal coverage.
