HiBoost Plus Series – Support Page

Using the Signal Supervisor app, you can connect to the booster and determine if the booster is working optimally. You can also use the LCD display to read the live status of the booster.

The type of booster you need depends on multiple factors including coverage area, indoor environment and outside signal strength.

Follow our easy selection matrix on the home page to determine which cell phone signal booster will work best for you.

If you have a blinking ISO, then you have some oscillation between the outdoor antenna and the indoor antenna.  Make sure that they are separated by 20ft minimum, and vertical distance is more important than horizontal distance.

We use carrier grade technology and innovative housing for our boosters.  They can operate in high degree temperatures of 150 degrees Fahrenheit.  If you feel like your booster is overheating and not providing any signal improvement, please contact us at 972-870-5666 or online at support@hiboostusa.com

The ALC or Automatic Level Control will automatically adjust the gain on a booster based on the current signal environment.  If you ALC is flashing, this just indicates the automatic gain control is working properly.

Our recommended distance is a minimum of 20 ft between both boosters and that distance be more vertical than horizontal.  If you are in a space limited area it is quite possible you can provide a blockage of signal by using certain materials between the two antennas.

Make sure you don’t have any flashing alarm or ISO lights.  Make sure your antennas are separated by a minimum of 20 feet.  Look to see if any of your cellular bands are turned off.  Adjust your outdoor antenna to fine tune your equipment.  If you are still having trouble, please feel free to contact us.

If you seem to have less coverage, this can be caused by several different issues.  First check your connectors are firmly tightened.  Check to make sure you have ample distance between the outdoor and indoor antenna.  Make sure they are not pointing at each other and that your outdoor antenna isn’t pointed across your building.  Check the gains on your booster and make sure the ALC is flashing and it is adjusting.  In some cases, you may need to manually adjust the gains, or you may need to adjust your outdoor antenna.

Yes, you can extend your coverage using one external indoor antenna and the built-in booster antenna. You can use two external indoor antenna with the booster but the built-in booster antenna will shut off.
