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
20’ 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 4KMR-30U system is designed to provide optimal coverage for up to a 1,000 SF to
2,500 SF
interior area (1 room).
Interior coverage varies based upon the outside signal
strength
and the interior building construction and materials. Typically the 4KMR-30U
system will NOT penetrate an interior wall or floor. To increase interior coverage area, use
one of Digital Antenna’s high gain outside and/or inside directional 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 20 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
DA4000MR repeater unit within 6’ of a 12VDC power receptacle. If the location
of the DA4000MR unit is not mounted within reach of the supplied 30’ cable, a
25’ extension cable and 75’ or 100’ replacement cables are available (sold
separately). The DA4000MR unit is not waterproof and must be mounted in a dry
location.
c. ELECTRICAL POWER
To maximize installation flexibility, the 4KMR-30U system includes 2 power cord
options.
WARNING!
Only the provided power cables are to be used with the 4KMR-30U
system. Using any other power cables will harm the DA4000MR
amplifier/repeater unit, can be detected and voids the warranty.
