Shopping Guide

Outdoor Antenna Selection:

Yagi Antenna –  Directional antenna, which mean it must point to mobile base station for better performance. Ideal for rural areas or properties with very weak outdoor signal. suitable to mount on a pole and thus can mount on existing pole used for TV antenna. Hiring of antenna installer or handyman is recommended.

Panel Antenna –  Outdoor antenna with wider reception angle. Ideal for most properties with acceptable outdoor signal. Suitable to mount on pole, concrete wall, wood, or window railing.

High Gain Log Periodic Antenna – High gain directional antenna that can receive wide frequency band, suitable to mount on a pole. Upgrade to this antenna for better signal performance.


Optional Extension Cable:

The outdoor antenna cable is 5m as included in standard package, this may not be enough for some case. Fortunately, the extension cables of 5m, 10m, 15m and 20m are available, please estimate the distance between outdoor antenna and repeater and purchase the extension cable accordingly.


Other Accessories: 

The booster package could function well without any other accessories. However, you could improve the indoor signal coverage with the purchase of indoor omni-directional ceiling antenna, power splitter and etc. Please visit to the link Mobile Booster Selection Guide if you would like to have more information regarding accessories that could help to improve your booster performance.


Explanatory Notes

What is AGC function ?

AGC means Automatic Gain Control; it means the booster can control the gain by itself according to the surroundings. When there is a sudden strong signal input, the booster can adjust the gain accordingly to protect the booster module and make sure the strong signal will not affect the base station signal.

When the signal outside is too weak, the booster can adjust the gain to maximum to boost the signal received at most for end user.

The AGC repeater come with LED indicators, it can show the running state of the booster, in case the booster and antenna installation is not right that cause loop oscillation, the LED light will indicate to user so user would be able to known and adjust the installation setup accordingly to avoid loop oscillation issue.


What is Auto Shut Down Function?

When the installation is not right that cause bad loop oscillation, the signal emit from the booster and antenna may jam the base station signal and affect to other users. Auto shut down function is to shut down the booster automatically when deep loop oscillation is detected to avoid jamming the tower and save your trouble from operators.
