INBUILT ANTENNA: Another great feature of the booster is the in-built indoor antenna that allows the booster to transmit full signal coverage without the need for extra indoor antenna. There is an option to add extra antennas to the booster without the need for a splitter. The indoor antenna keeps your ceiling free of antenna hanging from them and because you don’t have to install any indoor antenna you actually save a lot of installation time.

Hi23-5S Mobile Phone Signal Booster Smart LCD Functions

Hi23-5S Mobile Phone Signal Booster Real-Time Monitoring 

You take control of the current working status of your booster through the Information on the gain, frequency, and output power displayed on the LCD of the booster.

Troubleshooting: 

Displays faults and shows you where and how to fix them

Installation Assist: 

Locate the best position with good signal outside for the outdoor antenna to be mounted,  by displaying the outdoor signal strength on the screen.

Automatic Gain Control

AGC automatically measures and adjusts incoming signals strength and only allows strength needed for coverage in your area to be released. This feature helps prevent interference and frequencies overlap.
