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 outside antenna must be
installed outside of the building, RV or boat. The inside antenna must be mounted in a
central location in the building that is 40’ or greater from the outside antenna. The inside
and outside antenna also must be separated by an exterior wall. Two power supplies are
included to maximize installation flexibility.
Typical In-Building Coverage
The DA4000SBR system is designed to provide optimal coverage for a 3,000 ft

to 5,000
ft

area. Interior coverage varies based upon the outside signal strength and the interior
building construction and materials. Typically the DA4000SBR system will penetrate 1-2
interior walls and 1 floor based upon construction material.
Pre-installation Considerations
Establish a site installation plan based upon desired central 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 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 or on the side of the RV. On a boat the outside antenna
should be mounted clear of metal objects, 3’ from other antennas and as high as
possible.
•
For maximum coverage the location of the indoor antenna should have a direct
line-of-site to as much of the coverage area as possible. The indoor antenna must
be used with 18” cable and antenna stand. Never use the inside antenna directly
connected to DA4000SBR amplifier/repeater unit.
•
Based upon the desired coverage area, choose a central location for the
DA4000SBR unit. The location of the DA4000SBR unit must be accessible
within reach of the supplied 50’ cable (
TM
25’ extension cable and
75’ replacement cables sold separately) and within 6’ of a power receptacle (or an
extension cord can be used). The DA4000SBR unit is not waterproof and must be
kept in a dry location.
c. ELECTRICAL POWER
To maximize installation flexibility, the DA4000SBR system includes 2 power cord
options.
WARNING!
Only the provided power cables are to be used with the DA4000SBR
system. Using any other power cables will harm the DA4000SBR
amplifier/repeater unit, can be detected and voids the warranty.
