Section # 3 Selecting a Suitable Location to Install Your Booster

 

 

All antennas must be mounted a minimum distance of 40 cm (15.75 inches) away from any person(s). 

 

 

 

 

All installations must be in a dry area away from any fumes, hazardous materials or dangerous location. In addition, the booster’s 
location should be easily accessible and mounted away from moving parts, excessive heat or moisture. 

 

When installing the exterior omni directional antenna the antenna must be a minimum of 18” above any roofline or 
obstruction. 

 

If installing an external Yagi antenna inside an attic space of a building the walls and roof area must be made of wood, or 
wood with vinyl siding covering, asphalt style roof shingles, or cedar style roof shingles. This antenna will not work if the 
exterior walls are brick or concrete, or the roof is of metal composition, or metal decking. 

 

There is a minimum of six feet of vertical separation needed between the booster and antennas making sure there is a solid wall 
between the booster and antenna. 

 

Interior antenna(s) must be mounted in a position on the ceiling in an area that offers the widest range of coverage. If the area is 
larger than the antenna can cover, an optional power splitter / divider and antenna may be purchased from

After installing the booster if you do not realize an increase in signal levels, it may be due to location of the exterior or internal 
antennas. This can be overcome by re-positioning the antennas.  

 

The automatic gain control in the booster requires the exterior and interior antennas be connected 

PRIOR

 to powering up the 

booster. The green LED on the booster will blink while the unit is determining the proper gain level to prevent oscillation and 
interference, when the LED becomes solid the setting is permanent for that installation. If the power is disconnected, the booster 
will need to go through this process again. 

WARNING:

 

REMEMBER Prior to moving either antenna the booster’s power 

must be disconnected. Only after re-positioning the antennas should the booster be powered up again.

 

 

Section # 4 Installation Procedures When Installing your Interior Mount Antenna 

 

Place the interior patch antenna in a central location on the top floor of building. Place the adhesive side of the antenna flush with 
the ceiling. If the ceiling is fire rated style with foil backing, you must peel the foil backing away from the area the antenna will be 
placed in, to allow the full penetration of the RF signal through the material. Note: Make sure the interior antenna is a MINIMUM 
distance of 20 cm (7.87 inches) away from any person and 6ft from the booster.  

 

Home or business installation requires following the standard installation procedures detailed in the prior section of this installation 
manual. The drawing that follows is a typical installation in a home or business.

             

 

 

                                                

 

 
    

     

 

 
 
 
 
 
 

 
 
 
 
 
 
 
Section # 5 Final Installation Procedures  

 

If sections of the building are still experiencing low signal levels, it may require the purchase of a power divider /splitter and 
additional interior antennas.  These antennas should be installed in the ceiling of the area where the signal is weakest. Attached 
the antennas to the power divider / splitter and then to the booster.  Power the booster up and make sure the pilot light is solid.
