Who wouldn’t want to work with the comfort of great cell phone signal coverage?

In the smart world in which we live in, having stable connectivity on phone calls and internet data is imperative whether you’re at the office or at home, so a smart booster is what you need.

This Smart Cell phone signal booster comes in a full kit with all the components for installation and use. The system is plug-and-play and you’ll manage to mount it even without professional assistance in 4 easy steps.

STEP 1. Mount the outdoor antenna at a reasonable height.  Ideally on a pole on top of the roof pointing in the direction where signal reception outside is best and strongest.

STEP 2. Place the booster and the indoor antenna within the area where signal needs improvement.

STEP 3. Connect the antennas with the coax cables provided and plug the booster in the mains.

STEP 4. Once the booster is plugged to a power supply, you’ll then immediately start to enjoy perfect calls and blazing data download & upload speed (depending on the solution that you choose)! The system self-adjusts best parameters for your area in 30 seconds once the unit has been turned on.

Note!!! For high power models installation such as Hi20-XXX and Hi23-XXX we STRONGLY recommend to address to professional installers.

GSM+3G dual band amplifier HiBoost Hi20-EW is an efficient way to get rid of slow 3G speeds and constantly dropped voice service! From now on you won’t miss a call or message and will stay always reachable for your colleagues and partners.

The model coverage is up to 1500 – 4000 m2. Hi20-EW will easily spread strong signal around such indoor locations as a large house or villa, business center, shopping mall, supermarket. hotel, etc.

It comes in an elegant metal body equipped with real-time LCD display. Thanks to smart AGC function the system will auto set up the best performance for your area in seconds.

Buy it now and improve the quality of your everyday and business mobile communication!

*Mind that in order to achieve full performance of your cell phone booster you should have at least 2-3 signal bars outside your house, office, etc.


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.


Automatic Gain Control (AGC)

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 up to zero.

Manual Gain Control (MGC)

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


HiBoost Hi20-EW model comes in a kit with the following components:

  1. a mobile signal booster
  2. an outdoor panel antenna
  3. 50ft (15.2m) HiBoost200 cable
  4. 12V/3A, AC/DC power supply
  5. mountings
  6. a user manual
