How a HiBoost Cell Phone Signal Booster Works


How HiBoost signal boosters work.

HiBoost’s compact and powerful Home line of signal amplifiers can be installed quickly and efficiently without the need for professional installation services. Our signal repeaters are bi-directional, meaning they both send and receive signal both ways. The outdoor antenna is placed outdoors on the roof. This antenna will receive the signal from the nearest cell phone towers. It will then send the signal along the coaxial cable to the booster indoors. The signal booster will then take the signal, amplify and augment it, and send it down the other coaxial cable to your indoor antenna. The indoor antenna then re-broadcasts the strengthened signal into the surrounding indoor space where it is received by mobile and smart device users in the area of effect.

When a user’s cell phone or smart device transmits a signal, the process goes in reverse. The indoor antenna will pick up the user’s signal, amplify it with the signal repeater, and send the signal back through the outdoor antenna where it will be picked up by the cell phone tower. Users of signal boosters get to enjoy clearer calls, faster data downloads, and up to a 65% increase in battery life of mobile devices within range of the amplified signal. Simply put, HiBoost signal boosters Boost Your Bars!

The Importance of Doing a Soft Installation

After you have thoroughly read through the instructions, it’s time to set up a soft installation of the equipment. Placing the equipment where it needs to go before actually installing it will save you time and trouble if you find you need to move things slightly to get the best signal. Once you have things placed, double check your signal strength to ensure your placement will optimize your booster’s potential to get the best amplification. Make any adjustments needed in placement. This step is often critical to getting the most out of your booster.

Checking Cell Signal on Site

We find that the majority of problems users run into during installation are caused by failing to understand the importance of the proper placement of the outdoor antenna. In the spirit of “measure twice, cut once,” it is highly recommended you check and double check the cell signal received in your desired placement before fully mounting the booster and its components to their permanent location in your home. Failure to do this means you risk not gaining the full amplification of which your signal booster kit system is capable.

Field Test Your Signal

To briefly recap, you can use a signal amplifier, a signal reader meter, or a cell phone. To use your cell phone to read the signal, it is most beneficial to put it into field test mode or a mode where you can read the received signal in decibels (dB), not the typical bars readout. This can be done with an Android phone by downloading an app such as LTE Discovery. For iPhones, it can be slightly more difficult especially if you are using one of the newer models. For help doing this, we recommend checking out this helpful guide from one of our vendors, RepeaterStore.


Check the correct numbers on the LED display during installation.







Please Note: Whichever method you prefer to use to measure your received signal, be aware that the antenna must be able to pick up the signal from a cell phone tower in order to operate correctly. The booster can only amplify received signal; it cannot make it on its own.

The Installation Process

Check multiple spots on the roof for optimal installation.

Using whichever above method you prefer, move around the top of the roof of the building. Test at least five different locations (as iSafety first sign.n the image above) and determine where your best-received signal from the towers is located. Ideally, the outdoor antenna should be mounted on the roof and fit snugly and securely in its location. Typically the ideal location is at the highest point and free of obstructions such as chimneys, roofing, or tree branches. Please use extreme caution during this process. Make sure you do not place the outdoor antenna near aerials, high voltage cables, or transformers. Use extreme caution to make sure that the antenna and yourself do not come into contact with any power lines.

Outdoor Antenna

If your kit has a Yagi or another directional antenna, it has to be installed horizontally with the elements oriented vertically. Make sure there are at least three feet of unobstructed space around the Yagi antenna. Yagi antennas must never be pointed toward the inside antenna; this will cause oscillation and gain reduction in your signal. For any kind of outdoor antenna, ensure that there is at minimum 20 feet of space between the antenna and any users during normal use.

If your kit included an omnidirectional antenna you will not need to orient it in a particular way. Simply find the location with the best signal and install it at this location.

When you have found the ideal spot for your antenna, mark this location with tape or another temporary marker. Set up your outdoor antenna in that spot and then move on to the next step.

Indoor Antenna

Next, set up your indoor antenna. The preferred location for the indoor antenna is in the corner of common areas, such as the kitchen, living room, etc… Failure to keep the appropriate amount of distance between the outdoor antenna and indoor antenna will cause the booster to cease functioning properly in some cases this can even lower the amount of signal received. 

If you are using a dome antenna you must be able to access the ceiling above the area that you plan on installing your antenna. Please refer to your user manual instructions for the proper distance between the two components for your specific booster kit.

Signal Booster Location

Find a suitable place to mount your booster. Ideally, it should be away from heat and light and located near an outlet and in a well-ventilated space. We recommend that it be placed on a wall or mounted to the ceiling. Note the most ideal space for your booster and mark it. Remember that the signal does not transmit from the booster itself so it is more important for the booster to be placed in a safe, out of the way place. 

Connecting the Cables

Carefully run the cables from each item to connect all three. During your soft installation, double check that you have the proper amount of cable to connect your antennas to the booster. We highly recommend wrapping the outdoor cable connections with waterproof tape to prevent any moisture from harming the connection. Do not wind the outdoor cable. The cable from the outdoor antenna should be laid out in as straight a manner as possible to prevent signal loss.

If you are running more than 50 feet of cable you might want to invest in higher quality cable as well. If you upgrade from 75 ohms to 50 ohms coaxial cable you can increase the end decibel gain by approximately 2 dB. This can really add up especially as you keep adding cable.

Attach your cables properly from the outdoor antenna to the booster, and then the booster to the indoor antenna. Now then, plug in the booster to the power supply. Make sure the smart startup has finished and that the booster’s lights are flashing properly. Check your user manual or our pdf here to understand what the booster’s lights mean. Anything other than a slowly blinking green light on your booster means you will have to refer to the Troubleshooting section of your user manual to find a solution.

Check Your Signal Strength Again

Now, use your mobile device to make sure you have adequate signal coverage within the signal amplifier’s area of effect. If you are not satisfied with your coverage or the signal coverage is unstable, reread the instructions in your user manual, and make adjustments to the antenna position as necessary so you get the most optimal coverage from your signal booster. You can always call our technical support for some assistance in getting the optimal signal improvement. 

Final Installation

If your signal coverage is good and you are satisfied with the results, go ahead and install the booster and its components into their final positions according to manual instructions.  For troubleshooting purposes, you should be seeing steady green lights on all LED lights. None should be red.

Additional Components

Every home is unique, and so are your needs. Some users may find they need additional components or accessories. Our HiBoost Home kits have coaxial cables included, but some homes may need additional lengths of coaxial cables so that you can properly connect your antennas to your amplifier to get the best signal coverage. Some homes may also need splitters and multiple indoor antennae to provide the best signal coverage over multiple rooms. If you find you need more cables or additional antennae, or need arrestors for surge protection, we make and sell additional components and accessories on our website.  You can customize any cell signal solution with these accessories and some ingenuity.
