5. Installation 

5.1 Antenna Installation 

This is one of the most important processes in repeater installation, which gives very important influence 

to the performance of this equipment. 

 
5.1.1 The system includes two omni directional antennas, one is for indoor and the other is for outdoor. 

First, decide a place to install the outdoor antenna, and then attach the antenna bracket to the selected place. 
Before attaching the bracket, fix the antenna firmly to the bracket by using a connector.

5.1.2 Once the antenna bracket with a connector is fixed as shown in Fig. 5-1, bring the coaxial cable to 
the place to connect with the repeater body. 

 
5.1.3 Install the indoor antenna. In addition to an omni directional antenna supplied as basic accessory, 
this repeater may include a patch antenna as an option. The basic antenna should be pre-connected to the 
antenna connector in the lower part of the repeater, while the patch antenna should be connected to the 
direction for the cellular phone users.
