Step 2: Donor Antenna Installation
Mount the Yagi donor antenna outside the building facing the strongest cell tower. Ensure it is positioned high and facing away from the expected coverage area inside the building.

Step 3: Install the Donor Antenna
Follow the instructions from Step 2 to install the donor antenna in the location with the strongest signal, facing towards the cell tower.

Step 4: Run the Donor Antenna Cable
Run the cable from the donor antenna outside the building to inside. Be cautious of existing electrical wiring and outlets when drilling a hole through the wall. Do not share TV cables for the cell booster.

INTRODUCTION

SDRC-17 has been designed to improve and extend cellular coverage inside the buildings. It amplifies signals from the nearest base station and re-transmits them at higher power level and provides service at 700MHz, Cellular, PCS, AWS-1 band frequencies without any additional setup or configuration.

Application Example

Installation Guide

Step 1. Find the Strongest Signal

Using an iPhone (Dial *3001#12345#*, then press Call)

Using an Android (Download the “Network Signal info” from the Google Play store)

[Note] The stronger the signal you receive from the base station, the better coverage you will have inside your building

Step 2. Easy Outside Antenna Installation

The donor antenna must be mounted outside of the building pointing to the strongest cell tower. Mount the donor antenna as high as possible facing towards the desired location of the cell tower and facing the opposite direction of the expected coverage area inside of the building as shown in Figure 4-3 below

Correct Donor/Server Antenna Position
For the best performance, a minimum of 50 ft. distance between donor antenna and server antenna is recommended. Maximizing the isolation between the donor and server antenna is crucial to the RF performance of the system. Higher isolation allows for higher gains on the system which allows for higher output power which translates to a larger coverage area. If a system lacks isolation between the donor and server antenna, then this could lead to oscillation in the system which is a continuous feedback loop of the signal which can impact the performance of the system and also damage the equipment. When placing the donor antenna, obstructions such as concrete walls or thick materials can help increase the isolation between the donor and server antenna.

Step 3. Donor Antenna Installation
Install the donor antenna in the location to receive the strongest signal according to the instructions of Step 2. Make sure the donor antenna is installed facing toward the cell tower

Step 4. Run the Donor Antenna cable

When mounting the donor antenna to the outside wall of your building, the easiest way is to run the cable on the outside of the wall and attach it to the exterior of your house or building.

Then drill a hole through the wall which will allow the cable to appear on the inside of the building. Avoid any potential harm or damage; make sure that there are no electrical outlets, cables, or electrical wiring in the wall before drilling.
Note: TV cables already being run for other purposes cannot be shared with the cell booster during installation.
After drilling the required hole, run the cable through and seal it. In some instances, it may be possible to run the cable up into the fascia of the attic overhang. In this circumstance, the cable will be accessible in the attic further routing.

Step 5. Easy Server Antenna Installation

Select a location to install the server antenna.
Drill a hole in the ceiling where the server antenna will be installed.
Disassemble the nut assembled with the server antenna.
Drill a hole and insert the server antenna into the ceiling texture as shown above
Secure the antenna body with the nut.
Connect the server antenna cable to the server antenna.
Connect the cable connected to the server antenna to the SDRC-17 server port.

Step 6. Easy Rack Mounted Installation
Choose a location for the signal booster, preferably away from excessive heat, direct sunlight, moisture and is free from high temperatures. Do not place the signal booster in an air-tight enclosure. Attic installations may expose the booster to high heat.

Note: Please assemble only the screws according to the following procedure.

SDRC-17 Rack Mounting

Step 7. Easy Wall Mounted Installation
Choose a location for the signal booster, preferably away from excessive heat, direct sunlight, moisture and is free from high temperatures. Do not place the signal booster in an air-tight enclosure. Attic installations may expose the booster to high heat.

Troubleshooting

In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem. In most cases of major repairs, ADRF will simply replace the unit and conduct repairs at the appropriate facility.

Check LED status at rear of module
- Green LED on: Normal operation with maximum allowable gain.
- Red LED on: Shutdown by oscillation condition or over output.
Check external and internal connectors to ensure that all connections are tightly secure.
If user thinks there is a serious problem, call after sales team for over-the-phone technical support. Tel: 818-840-8131

Functions

ALC (Auto Level Control)
ALC maintains limit of the output power in order to protect bad influence to the Base Station.

AGC (Auto Gain Control)
The Signal Booster checks isolation between inside and outside antennas once a day.
AGC sets up downlink and uplink gain value automatically depending on the input power level.

ASD (Auto Shutdown)
There are two cases when ASD works.

Outside antenna and Inside antenna are not isolated enough from each other.
So in order to protect the Signal Booster from damage, it will automatically shutdown at this frequency.
Uplink Signal coming from the outside antenna to Base Station is too strong and may cause troubles to carriers network, so the Signal Booster will shutdown at this frequency.

FCC warning statements

FCC Part 15.105 statement Class A
This equipment has been tested and found to comply with the limits for a Class A digital device,pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense.

FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.

RF Exposure Statement

The antenna(s) must be installed such that a minimum separation distance of at least UL : 55cm,DL : 20cm is maintained between the radiator (antenna) and all persons at all times. This device must not be co-located or operating in conjunction with any other antenna or transmitter.
Use of unauthorized antennas, cables, and/or coupling devices not conforming with ERP/EIRP and/or indoor-only restrictions is prohibited.

If the Signal Booster is not in use for 5 minutes, it will reduce gain until a signal is detected. If a detected signal is too high in a frequency band, or if the Signal Booster detects an oscillation, the Signal Booster will automatically turn the power of on that band. For a detected oscillation the
Signal Booster will automatically resume normal operation after a minimum of 1 minute. After 4 minute such automatic restarts, any problematic bands are permanently shut off until the Signal Booster has been manually restarted by momentarily removing power from the Signal Booster.

Noise power, gain, and linearity are maintained by the Signal Booster’s microprocessor. The detailed information was included in the Operational description.
