of the building. (see specific section for Home/Office, marine and RV installations) The omni-directional antenna should be installed on the side of the building with the strongest cellular signal as indicated by the bars on the cell phone. The inside antenna must be mounted in a central location in the building, RV or boat that is 40’ or greater from the outside antenna with as much vertical separation as possible. Vertical separation is better than horizontal. The inside and outside antennas also must be separated by an exterior wall and roof. Two power supplies are included to maximize installation flexibility.

Typical In-Building Coverage

The 5KSBR-50U system is designed to provide optimal coverage for up to a 3,000 SF to 5,000 SF interior area. Interior coverage varies based upon the outside signal strength and the interior building construction and materials. Typically the 4KSBR-50U system will penetrate 1-2 interior walls and 1 floor based upon construction material. To increase interior coverage area, use one of Digital Antenna’s high gain outside and/or inside directional antennas or use a cellular combiner and multiple inside antennas. (pg 15).

Pre-installation Considerations

Establish a site installation plan based upon desired interior coverage area

•The inside and outside antenna must have a separation distance of 40 feet or greater, the outside antenna must be outside and separated from the inside antenna by an exterior wall and roof, and both antennas must be in a vertical position.

•Identify the outside antenna location. If the outdoor coverage area is very poor, the outside antenna should be placed on the side of the building where the signal is the strongest. If the signal is equally strong outdoors, the outside antenna should be placed in a secure, unobstructed area. On an RV the antenna can be attached to the back ladder. On a boat the outside antenna should be mounted clear of metal objects, 3’ from other antennas and as high as possible.

•For maximum interior coverage the location of the indoor antenna should have a direct line-of-site to as much of the coverage area as possible. Never turn the repeater on without antennas and cables securely attached.

•Based upon the desired interior coverage area, choose a central location for the DA4000SBR repeater unit within 6’ of a 12VDC power receptacle. If the location of the DA4000SBR unit is not mounted within reach of the supplied 50’ cable, a 25’ extension cable and 75’ or 100’ replacement cables are available (sold separately). The DA4000SBR unit is not waterproof and must be mounted in a dry location.

c.ELECTRICAL POWER

To maximize installation flexibility, the 4KSBR-50U system includes 2 power cord options.

WARNING!

Only the provided power cables are to be used with the 4KSBR-50U system. Using any other power cables will harm the DA4000SBR amplifier/repeater unit, can be detected and voids the warranty.
