4.安装示意图
安装途径

修正了室外天线接收的屋顶和指向信号塔。
通过电缆连接室外天线，以​​“户外”端口中继机。
通过电缆连接室内天线（S）以“室内”端口中继机也。
插上电源适配器插入交流电源插座，并完成安装。

技术支持

如果仍然没有收到信号中继器启动后，请检查室外天线指向信号塔或其它地方具有强烈的信号，并检查强度达到-70dBm。
如果不能调出，请调整室外天线的方向。
如果实力不平稳，请检查室内室​​外天线太近。 请确保室外和室内天线有距离20

5.附件
SelectionOutdoor天线使用7单元八木型天线，室内天线使用板或屋顶天线和信号线使用同轴电缆。

4. Installation Sketch Map
Installation Approaches

Fix up outdoor antenna reception on housetop and point to signal tower.
Connect outdoor antenna to 'outdoor' port in repeater machine through cable.
Connect indoor antenna (s) to 'indoor' port in repeater machine through cable also.
Plug power adaptor into AC power socket and finish installation.

Technique Supporting

If still no signal receipt after activated repeater, please check if outdoor antenna point to signal tower or elsewhere have strong signal and check if strength achieve -70DBM.
If can not call out, please adjust the direction of outdoor antenna.
If strength is not steady, please check if outdoor & indoor antennas are too close. Please ensure the outdoor and indoor antenna have distance of 20

5. Accessories
SelectionOutdoor antenna use 7 unit yagi type antenna, indoor antenna use board or rooftop antenna and signal wire use coaxial-cable.
