In order to achieve the best signal coverage effect, there is a certain distance
requirement between the inside antenna and outside antenna. Make sure that the
outside antenna is horizontally attached to the roof and the inside antenna is parallel to
the horizontal plane.
First determine the location of the inside antenna. It should be the place you use your
cell phone signal most of the time.

location that the cable can reach.
