Section 4 Installation Instruction
4.1 Before Installation
Please verify the uplink and downlink frequencies labeled on the equipment, ensure they
match with your PO and your system requirements. Please contact your sales
representative if you find any discrepancy.
Install the equipment only in a normal indoor environment.
The built-in signal strength indicator supports quick deployment without additional tool and
equipment. However, we highly recommend that if possible, always use spectrum analyzer
and other equipment to assist the installation. Ideally, donor signal strength should have
been measured prior to the installation and the link budget and coverage have been
calculated by certified RF system design engineer. BOM, test plan and other documents
must be in place prior to the installation.

Fig.2 Installation Procedure
1. Find a proper indoor position where a good grounding path is available, usually
on a wall, and install the REPEATER following the steps given in the QUICK
START.
2. Follow the system design documents to locate the donor antenna ad service
antennas. The donor antenna and service antennas must have sufficient isolation,
and 90 dB minimum is recommended to ensure the device is working normally.
Donor antenna is typically installed on the rooftop or outside wall with high elevation,
avoiding any obstacle and in line of sight with the base station antenna. The
positions and number of service antennas must be designed properly by a qualified

system design engineer with proper RF planning tool.
3. Route the feed lines from the donor antenna to the REPEATER and service
antennas to the REPEATER following the system design documents. Connect
the feed line to donor antenna, and feed line to service antenna. Waterproof
the connections. Do not connect the feedlines to the REPEATER.
4. Verify isolation between donor antenna and service antennas. If a network analyzer
is available, it is recommended to verify the isolation between the donor antenna
and service antenna by bypassing the REPEATER and testing the transmission
between the port of the feedline to donor antenna and the port of the feedline to
service antenna. Minimum of 90dB is preferred. If the isolation is less than 85 dB,
report to your project manager and system design engineer. Relocate the donor
antenna, or service antenna might be necessary. If both options are not applicable,
then the REPEATER gain needs to be adjusted to avoid self-oscillation which
needs approval from the project manager and system design engineer, refer to
step 10
5. Adjust the donor antenna orientation.
5.1 If spectrum analyzer or other equivalent RF signal strength measurement
equipment is available (Highly recommended):
5.1.1 Set the spectrum analyzer's frequency range, bandwidth and other
parameters.
5.1.2 Connect donor antenna to the input port of spectrum analyzer.
5.1.3 Adjust donor antenna direction until -45dBm to -55dBm signal strength is
measured.
5.1.4 Connect the donor antenna port to the REPEATER ‘BS’ port.
5.2 Install the donor antenna without spectrum analyzer:
In case spectrum analyzer or other equivalent RF signal strength measurement
equipment is not available, the “Alarm” indicator on the front panel can be used to
adjust the donor antenna direction. When signal strength received from the donor
antenna is lower than -48dBm, the indicator is green; when the received signal
strength is higher than -35dBm, the indicator is red; when the received signal
strength is between -45dBm and -38dBm, the indicator is orange. It is suggested
to adjust the direction of the donor antenna to make the indicator just change
from green to orange which indicates the received signal strength is around
-48dBm.
5.2.1 Adjust the donor antenna direction until the “Alarm” indicator just change
from green to orange.
5.2.2 Connect the donor antenna port to the REPEATER “BS” port.
User Manual of
Dual Band Adjustable Repeater RF37GS-PS7080
www.rftoo.com
If the “Alarm” indicator stays green when you change the donor antenna direction,
this means the donor signal is too weak and you will get degraded coverage even
no coverage. Following are what you need to do
5.2.3 Immediately report to the project manager and system design engineer.
5.2.4 Recommend to confirm the signal strength using a spectrum analyzer if
possible.
5.2.5 Work with your project manager and system engineer, check if you can
replace the donor antenna by a higher gain antenna to get better signal.
5.2.6 Work with your project manager and system engineer, check if you can
relocate the donor antenna to get better signal.
6. Connect the service antenna to REPEATER’s “MS” port.
7. Set all attenuation switches on the ATT switch panel to off position, unless the
system design document requires to reduce the uplink and down gains from
factory default values.
8. Check and ensure “BS” and “MS” ports are connected to feedlines.
Connect the power adapter and plug in the power supply.
Follow the test plan, walk test the call quality in the service area.
9. When it is needed, service antennas may be relocated to satisfy coverage
requirement. You will need to get approval from your project manager and
system design engineer.
10. During the walk test, if self oscillation (Refer to Section 3) is observed, this means
either the donor signal is too strong or antenna isolation is insufficient. Report to
the project manager and system design engineer. Repeat Step 4, 5 and 8 if
possible.
11. The gain of uplink or the downlink, or both needs to be reduced. Use the
combination of switches 1-5 for uplink and 6-10 for downlink to reduce the uplink
and downlink gain respectively. Repeat the walk test until the coverage is
acceptable. Document and report to project manager and system design
engineer on the gain value settlement.
Document the installation and test reports, and submit to project manager for approval.

Section 6 Notices
1. Never Turn on the equipment until both “BS” and “MS” are connected to Antenna.
2. Always remove excessive feed lines from the equipment to donor antenna and
service antenna to minimize the cable loss.
3. Always install the donor antenna at the most available highest position and keep
distance from the service antenna to maximize the isolation between each other.
The vertical distance between donor and service antenna should be more than 3
meters.
4. Certain isolation between donor antenna and service antenna are required to avoid
self-oscillation. In case self-oscillation happens, reposition is required for the
antennas.
5. The donor antenna must be placed at least 2 meters away from other antennas on
the same site.
6. All feed line connections must be waterproofed.
Self-oscillation: During the walk test, if handheld indicates there is signal but no
communication, this often means self-oscillation occurs. Check the Alarm indicator, if it is
red, this means the donor signal is too strong or antenna isolation is insufficient. Adjust the
downlink attenuation, if the red indicator disappears, then this means the donor signal is
too strong. If the red indicator does not disappear, or the red indicator disappears only if
both uplink and downlink ATT switches are on, this indicates that there is no sufficient
isolation between the donor antenna and service antennas.
