Warnings and Recommendations
Warning:
In a wireless installation, do not plug the amplifi er directly into 
the cell phone or cellular data card using an antenna adapter. It 
will damage the cell phone or cellular data card.
Warning:
Do not plug in the DC power supply until the outside and inside 
antenna cables are attached to the amplifi er.
Warning:
RF Safety: The inside antenna must be installed with a 
separation of at least eight inches from all persons and must not 
be located in conjunction with any other antenna or amplifi er.
Warning:
RF Safety: The outside antenna must be installed with a 
separation of at least 10 inches from any of the vehicle’s 
occupants or nearby persons and must not be located or 
operating in conjunction with any other antenna or amplifi er. All 
roof-mount antennas should be centrally located on the roof of 
the vehicle. Mirror-mount antennas should be at least six inches 
from the ground and leave at least 20 inches of separation from 
any persons near or around the vehicle. Use of this cellular 
amplifi er with an antenna gain higher than 6.12 dBi is in violation 
of FCC regulations for which the offender is fully liable. All 
Wilson mobile antennas are 6.12 dBi or less.
Separation of inside and outside antennas is very important. The metal 
roof of the vehicle acts as a barrier and helps shield the two antennas from 
each other, preventing oscillation. 
If the vehicle has a sunroof, it is important to separate the inside and outside antennas 
by at least fi ve feet. This prevents the amplifi er from overloading or oscillating.
Distance between antennas 
through a sunroof must be 
5 feet or more.
