NOTE: These instructions will walk you through a “ soft ” install process to find the optimal locations for the inside and outside antennas, then through the process of the permanent installation. 1 to 2 hours 2 people (a person to help with antenna calibration) pLadder pDrill (if routing cable through wall) p1”-3” diameter existing pole for mounting Outdoor Antenna (Pole Mount can be purchased separately if needed) pRecommended: Power Strip with surge protection 2 Step 1: Inside Antenna Placement Choose right position for the indoor antenna •1 feet away from any other metallic objects •3 feet away from any windows Place the Inside Antenna where you need the greatest signal boost and place Booster in your desired location. NOTE: Do not connect booster to power until the system is fully installed. 3 (STEP 1 cont.) Booster Placement Mount the booster •Choose a ventilated and dry place •Keep away from heat •Don't cover booster Booster will about 30 degrees Fahrenheit higher than the ambient temperature, which is a normal phenomenon. 4 Step 2: Mount & Point Outside Antenna Toward Nearest Cell Tower Pole mounting and wall mounting options are included. The pole mounting option is preferred because it will be easier to adjust to the direction of the cell tower. Attach the Mount to the Outside Antenna and use the Bracket Clamps to attach the Antenna to a pole or exhaust pipe. Make sure that the outside unit is mounted at least 3 feet away from any windows. Outdoor antenna must be installed over the roof line. NOTE: Mounting on existing roof exhaust pipe would be a good time-saver option. Watch out for power lines. 5 ①② ③ Point the Outside Antenna toward the nearest cell phone tower. To find the nearest tower, use an app such as 'Open Signal'. This is the most critical step of the installation process because it will determine the overall performance of the booster system. 6 NOTE: The Outside Antenna must be at least 40 feet (12 meters) Straight line distance or 30 feet (9 meters) horizontal 20 feet (6 meters) vertical from the Inside Antenna for best performance. Keep enough distance between outside and inside antenna The greater the separation between the Inside and Outside Antennas, the better performance you will get from the booster. 7 Select the optimal mounting location for the outside antenna 8 After identifying the area of strongest signal, choose the surface where you will mount your outside antenna. 1. The location should allow for sufficient separation between the outside antenna and inside antenna. 2. In order to better receive external signals, the outside antenna is best installed in a higher position on the house, but please pay attention to lightning protection. Antenna mutual position 9 The outside antenna should be oriented in a way that it does not “face” the inside antenna. Caution: Do not aim an outside antenna towards inside antenna. Caution: The inside antenna cannot face the outside antenna. Step 3: Route & Connect Outside Antenna To Booster Connect the white 3D-FB Cable to Outside Antenna and route cable into the home, secure the cable near the antenna. All connections should be finger tightened only. Route cable to the Booster and connect to the port labeled 'OUTSIDE'. 10 Step 3: Route & Connect Inside Antenna To Booster Connect the Inside Antenna to the 'INSIDE' port on the booster. 11 (STEP 3-A cont.) 12 Fasten bracket to back of Inside Antenna Secure bracket to wall Drill holes Tap anchors in Mounting Inside Antenna on wall bracket sideview Wall Mounting Option Step 4: Power Up The Booster & Optimize The System Plug in the Power Supply and connect it to the nearest power outlet. NOTE: We strongly recommend using a power strip with surge protection.

Test Setup: Test Procedure: a) Connect the EUT to the test equipment as shown in Figure 3. Begin with the uplink output (donor) port connected to the spectrum analyzer. When measuring downlink noise, connect the downlink output (server) port to the spectrum analyzer. b) Set the spectrum analyzer RBW to 1 MHz with the VBW ≥ 3 . RBW. c) Select the power averaging (rms) detector and trace average over at least 100 traces. d) Set the center frequency of the spectrum analyzer to the center of the CMRS band under test with the span ≥ 2 . the CMRS band. e) Measure the maximum transmitter noise power level. f) Save the spectrum analyzer Test Plots as necessary for inclusion in the final test report. g) Repeat 7.7b) to 7.7f) for all operational uplink and downlink bands. h) Connect the EUT to the test equipment as shown in Figure 4 for uplink noise power measurement in the presence a downlink signal. Affirm the coupled path of the RF coupler is connected to the spectrum analyzer. i) Configure the signal generator for AWGN operation with a 99% OBW of 4.1 MHz. j) Set the spectrum analyzer RBW for 1 MHz, VBW ≥ 3 .

This shall include all spectrum blocks in the particular CMRS band under test (see Appendix A). l) For uplink noise measurements, set the spectrum analyzer center frequency for the uplink band under test, and tune the signal generator to the center of the paired downlink band. m) Measure the maximum transmitter noise power level while varying the downlink signal generator output level from −90 dBm to −20 dBm, as measured at the input port (i.e., downlink signal level at the booster donor port node of Figure 4), in 1 dB steps inside the RSSI-dependent region, and in 10 dB steps outside the RSSI-dependent region. Report the six values closest to the limit, with at least two points within the RSSI-dependent region of the limit. See Appendix D for noise limits graphs. n) Repeat 7.7.1h) through 7.7.1m) for all operational uplink bands. Variable uplink noise timing Variable uplink noise timing is to be measured as follows, using the test setup shown in Figure 4. a) Set the spectrum analyzer to the uplink frequency to be measured. b) Set the span to 0 Hz, with a sweep time of 10 seconds. c) Set the power level of signal generator to the lowest level of the RSSI-dependent noise [see 7.7.1m)]. d) Select MAX HOLD and increase the power level of signal generator by 10 dB for mobile boosters, and 20 dB for fixed boosters. e) Confirm that the uplink noise decreases to the specified level within 1 second for mobile devices, and within 3 seconds for fixed devices.12 f) Repeat 7.7.2a) to 7.7.2e) for all operational uplink bands. g) Include Test Plotss and summary table in test report.
