*Mind that you should have at least 2-3 signal bars outside your house to provide overall strong signal enhancement. The device’s coverage also depends on building design features.

Built-In Indoor Antenna

HiBoost Hi17-3S booster is super easy to mount and use as it goes with a built-in indoor antenna. In other words, a standard kit includes an outdoor directional antenna only and there’s no need to drill a hole in the wall to fix an external indoor antenna inside your home or office.

  • Save time and efforts on installation
  • Escape from an antenna hanging on the wall and cabling
  • Place a booster wherever you want regardless of the indoor antenna position

Smart Link Function

There’s no other cell phone repeater on the market that can boast of remote control ability. Thanks to Smart Link Function you can connect your booster with your phone or tablet and manage the system with a mobile app via Bluetooth or Wi-Fi. The application you need is Signal Supervisor, it’s easy to download from Google Play or Apple Store.

  • Monitor and set up your booster anytime anywhere
  • Test your signal strength to find the best position for the outdoor antenna and to check the level of mobile signal enhancement
  • Get detailed info on your mobile network, serving cell tower, carrier, etc.
  • Share your device with an engineer for assistance

User-Friendly LCD Display

  • Real-Time Monitoring
  • Displays gain, frequency, and output power to let you keep control over the current working state.
  • Smart Troubleshooting
  • Detects and shows an exact kind of malfunction (ALC or ISO) giving you the cue what is necessary to fix.
  • Assistance in Installation
  • Helps to find best point for outdoor antenna mounting basing on the output power value displayed on the screen.


Smart AGC & MGC Functions

Automatic Gain Control

  • Intelligent System Setup
  • After the booster is on, AGC automatically measures input signal strength and adjusts best system parameters suitable for mobile signal reception conditions in your particular area.
  • Powerful Network Protection
  • AGC facilitates power control between the base station and a repeater to keep gain at the optimal level. This way HiBoost doesn’t overlap mobile network and keeps noise minimized.

Manual Gain Control

  • The function lets you thoroughly adjust mobile signal amplification power on your own manually. Recommended for advanced users.

Kit Options

Hi17-3S model standard kit includes:

  • mobile signal booster,
  • outdoor directional antenna,
  • 50ft (15.2m) HiBoost 200 cable,
  • 12V / 3A, AC/DC power supply,
  • power cord with European standard plug

If you need to extend coverage area from 1000 up to 1800 sq.m., you can add 1 or 2 external indoor antennas. There’re 2 kinds of optional kits available:1) Panel Kit : indoor panel antenna, 50ft (15.2m) Hiboost200 cable2) Omni Kit: indoor omni ceiling antenna, 50ft (15.2m) Hiboost200 cableChoose the one that best meets your needs!
