6
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.
