– such as indoor areas, underground parking stations and subway tunnels. The JL20 will receive RF signals from a LTE Base Station, amplify this signal then transmit this amplified signal to the desired coverage area. The maximum output power of the JL20 is rated at 20dBm for both the downlink and uplink paths. -
Page 6: System Description
2 | SYSTEM DESCRIPTION 2. System Description 2.1 Configuration The basic configuration of the JL20 is to receive and amplify the base station signal, then re- transmit this amplified signal to provide coverage for the desired area as shown in the figure below. -

Repeater units. 3.2 Handling of the Repeater As the JL20 Repeater is heavy, the installer should be careful and seek assistance while attempting to lift/carry/move the unit. To avoid the risk accidental fire or electric shock, do not expose the Repeater to rain or any other wet condition during installation. -
Page 14: Inspection Before Installing The Repeater
Confirm the correct accessories have been supplied. Installation Procedure 3.5.1 Repeater Cabinet Installation The JL20 can be mounted on a wall or the ceiling. This section describes how the Repeater can be mounted on three different surfaces – lumber, drywall (gypsum, plasterboard) and concrete. - Page 15 1) Using the timber screws specified in the figure below, firmly attach the Bracket B to the desired location. [Figure 10] Mounting Bracket – Lumber Mounting Repeater Operation Manual Version 2.00 Page 15 of 28 Model: JL20 ©2008 Juni | America Inc...
- Page 16 2) Drill four 6mm holes 30~40mm deep. Insert plastic anchors into the holes. 3) Firmly attach the Bracket B to the surface by using the screws as shown below. [Figure 12] Mounting Bracket – Concrete Mounting Repeater Operation Manual Version 2.00 Model: JL20 ©2008 Juni | America Inc...
- Page 17 Once Brackets A and B have been both installed, complete the mounting process by combing the two brackets as shown below. [Figure 13] Mounting Complete Repeater Operation Manual Version 2.00 Page 17 of 28 Model: JL20 ©2008 Juni | America Inc...

Page 28: Appendix 3. Risk Assessment And Control Form
Health and Safety Always read the Operations Manual before using the including Hazardous product. If in any doubt, consult your supervisor before Materials use. [Table 119] Risk Assessment and Control Version 2.00 Repeater Operations Manual Model: JL20 ©2011 Juni | America Inc... - Page 29 MPE Information Warning: Exposure to Radio Frequency Radiation The radiated output power of this device is far below the FCC radio frequency exposure limits. Nevertheless, the device should be used in such a manner that the potential for human contact during normal operation is minimized. In order to avoid the possibility of exceeding the FCC radio frequency exposure limits, human proximity to the antenna should not be less than 25cm during normal operation.
