5. Marine Installation 
 
Review pre-installation considerations and determine site installation plan.  
 
1.  Install supplied outside antenna (PN 288-PW) to vertical surface or pole with 
supplied hardware. Mount the outside antenna clear of metal objects and 
obstructions and as high as possible. Use PN F114 to mount 288-PW to 1”-14 
threaded basse. Outside antenna must be mounted in a vertical position. The 
4KSBR-50U system may also be used with one of Digital Antenna’s marine 9dB 
gain dual band cellular antennas (pg 15). (Follow minimum 40’ inside and outside 
antenna separation guideline) Antennas must be separated by a structure and a 
40’ or greater distance with as much vertical separation as possible. Vertical 
separation is better than horizontal.   
WARNING! - 
Only Digital Antenna authorized products may be used 
with the 4KSBR-50U system. Using unauthorized equipment will harm 
the 4KSBR-50U system, can be detected and voids the warranty. 
2.  On supplied 50’ cable (PN 340-50NM) (or optional 25’ extension cable or 75’ or 
100’ replacement 
PowerMax
TM
 cable) attach N male connector to N female 
connector on outside antenna. Secure cable to the side of the building with 
appropriate fasteners (not supplied). Route cable according to site installation plan 
to the DA4000SBR unit.  
3.  Attach mini-UHF male connector at the end of the supplied 50’ cable to 
DA4000SBR unit on the port labeled outside antenna. Attach the 6’ cable 
attached to the inside antenna and stand to the port labeled inside antenna. The 
inside antenna must be operated in a vertical position. DO NOT turn the 
repeater on until antennas and cables are securely attached.  
4.  The DA4000SBR unit has four mounting holes that can be fastened to a secure 
surface. (fastening hardware not included)  
5.  When using 110VAC - Plug 100-240VAC power supply to the DA4000SBR unit. 
Plug the other end into standard 110VAC receptacle. 
When using 12VDC – Plug the 12 VDC to 5 VDC power cable (PN DP515) into 
the DA4000SBR unit. Plug the other end into a 12VDC cigarette style power 
source. 
 
The 12 VDC power supply, PN DP515, has a micro-processor controller to turn 
the repeater off if not properly installed. If a red flashing light appears on the 
power supply, relocate the inside and outside antennas until the power supply has 
a constant green light. The power supply can be reset by unplugging the cigarette 
adapter from the power source.   
  
WARNING! 
To have DC power hardwired consult a professional electronic technician.  
 
6.  Turn the power switch to ON. If the light on the DA4000SBR unit is green and the 
coverage area is greater than 1-2’ then the 4KSBR-50U system is operating. Test 
the amplifier/repeater system by making a cell call and verifying that the indicator 
light does not turn red. If the light on the DA4000SBR unit is red immediately 
turn OFF the DA4000SBR unit and refer to the Amplifier/Repeater status section.
