How It Works
STEP-1
The outdoor antenna communicates and captures cell signal from the cell tower
STEP-2
The booster receives the outside signal, amplifies it and send it to the inside antenna
STEP-3
The inside antenna broadcasts the amplified signal to the area that needs reception
Here’s Why Customers Love Hiboost
It did boosts my bars!!
Working from home forced me to “boost” my mobile reception, and this gizmo took me from 1 bar to 3 bars. I can probably get to 4 bars with some additional tweaking after I get to a hardware store. It is critical to follow the installation instructions regarding antenna spacing as well as directions for both the indoor and outdoor antennas. It is worth spending a few hours to experiment with placement of the antennas.
Boosts my indoor phone signal!
I live in the country and have very little service. The cell phone signal booster has been able to boost my cell signal and provide me with 4 bars where before I only had 1 to 2 bars. I use my cell phone for a hot spot for my computer and it has been awesome!!!
Good product that actually works when installed properly.
I used this product to replace an old wireless booster after it met its end due to a lightning strike. After installing this product, I have found it to work better than my old unit being it not only boosts my AT&T FirstNet phone but also Verizon phones in the same house hold (At the same time). I live in an area of rural Georgia where towers are only 4 miles away but due to the topography, you have little to no signal at ground level. After installing the outside antenna on our TV antenna that is climbable (Aprox. 30’), I hooked up the unit and instantly received full signal on my device, works good on the LTE & 4G bands

What's the difference between the 4K Plus and 4K Smart Link?
In addition to different amplification, appearances, and prices, the indoor antenna of the Plus is built in the amplifier. You do not need to run extra indoor cable for the indoor antenna like a Smart Link booster with a panel indoor antenna. Besides the Smart Link is featured with a metal case while 4K Plus comes with an ABS case.

Unbelievable device!!! I live in a poor signal place and we have trouble with connecting with outside the world but now we can. I bought this for my factory and it also helped.
Willard Daniel –
The installation of this 4K signal booster is fairly easy. You have to hook up one antenna inside house and other is outside the house. There is an app to determine direction of cell tower for outside antenna installation. Installation took about an hour to set up and working properly. We live in a roughly 2K square foot home and this is more than sufficient. We live in a town and get good signal but some areas in the house get lost. This device captures those areas. So people living in very rural areas, this should help them out greatly.
Rob M. –
Love this booster. I like being able to adjust the signals from the different bands. I use this for my home internet hotspot and I see about 60 mbps increase over not having it hooked up.

The only thing I would warn someone is that is you must have a signal source or it won’t work. I live way down in a valley. We downloaded the app recommends and found out where our towers were around us and used one to locate the tower. We had to go 70 feet up to get the outdoor antenna to pull the signal from the tower, it was work, but well worth it. Now everyone in the house has there own internet so we are not trying to share 1 mbps between the four of us.
Kevin T Wilson –
I don’t have to stand at a window when using my cell phone inside.
Rural installation with signal outside but weak and sometimes no signal inside. Completed the antenna test setup using SignalSupervisor (Android) and was very pleased with inside signal strength. I used to stand at a window or go out on the porch to use my cell phone but I now have the ability to call and use data (with the WiFi Off) everywhere inside (used my phone for a few hours just with the Test Setup).

Will work under the right conditions
This is a seriously high quality and high tech item. It is not a toy in the least. It is very good for areas inside buildings where cell reception is poor. This type of item actually should be installed in schools and other brick buildings with large interiors so there is cell reception when away from the windows and outside rooms.
In terms of residential use this is not super practical because the installation is not very easy. There is an antenna that needs to be outside to work the best. Most homes have reception everywhere. This would work for a very large home with proper installation.
Another use would be if going somewhere with an RV or camper that has weak cell reception. This could be set up in a temporary way to allow phone calls and internet where it isn’t there normally.
This is a device that has a very specific purpose and is not a toy. If you have rooms that need reception this will work. It is just not a 10 minute install.

The customer service delivered by Aaron is what took this product from one of many being considered to a purchase.
After reading reviews that varied all over the highway he brought home the reality of use and proper install.
Now I have the unit installed and it works great.
Michael –
I live in the area with poor signal of any kind, cell, tv, radio. This cell phone signal booster has been able to booster cell signals and provide me with a 4 bars where there only used to be 0 to 1 bar. I have both Verzion and T-mobile, 2 different carriers, and both have great reception now.
Jim Keathley –
We recently switched providers and have good service outside but certain spots in our house have poor service. I installed the unit on the first floor and it gives us 3-5 bars inside our everywhere but our master bathroom which also gets poor wifi signal. Customer service has been great. When you call support, you get a live agent not a robot. Only negative is the large connectors they use on the provided cable. It requires a rather large whole(3/4 inch) to be drilled in your ceiling/wall/floor. Other than that, its been great.
Alex P. –
We moved from the big City to a rural village. This works great at pulling in the mobile phone signal from the outside and giving us something usable inside the house.
Giselle Suarez –
Great product, works exactly as it says. I was lucky to get one bar of signal, inside my house. After the Booster installation, I am able to get 3 to 4 bars all over inside my house.
Very pleased‼️
John –
Take time to install & follow directions
Used for another country with limited communications. Previous had no or sporadic cell service / signal.
Now communication 300% better. For elderly couple in case of emergency.
Other cell problems caused by power outages & carrier service not related to booster.
I used this for Venezuela & matched carrier frequencies to booster specs.
Very good product that was needed for a critical purpose.
IWYWH –
I have Metro by T-Mobile, and the signal isn’t too great in my house. Thought this would help, but didn’t do much. Installing was also a bit difficult, so definitely only get this if you have some knowledge about this stuff.
Tony Hopewell –
It seems to be working okay but I cannot give this item a99% yet.
John –
My wife and I have a cabin deep in the woods. Even though our signal isn’t 10/10 this product still helped us get 3 bars on our phones with Verizon. I highly recommend this if you are deep in the wood as well, but it doesn’t take a little bit of time to setup.
Jenner –
I really wanted to use this, but I can’t because we have to climb on a roof and install a flag pole (or similar) to get this to work. If I knew that, I wouldn’t have taken this. I thought it was just a box we could plug in. Anyway, my bad for not knowing. The rest of you have been warned. The four stars is because this looks like a high-quality product that would probably work if I actually installed it.
Tanya and Rob –
Unfortunately the product didn’t work the way it should. All our devices appeared to have full bars but went extremely slow.. even moved the device and antenna and still same problem.
Willow Choi –
This works great.We live in a valley high hills on both sides. The antenna reaches high enough to grab a signal.Mounted it top of the stairs and it pretty much covered both floors.It took some time to find the right placement and distance between the antenna and the booster but we dialed it in and now we’re getting 4 bars of cell service.
sean mark pickard –
Had a metal house built. Have 4 bars of cell service outside but zero inside. Tried almost very thing I could think of without spending a lot of money. Drop my prepaid and got on a contract to get Wi-Fi Calling. Which sucks because internet sucks where I’m at( barely better than dial up, if at all). And there is only one company that services the area I live in.(probably part of the problem). Decided (after researching for a while) to try the HiBoost 4K cellphone signal booster and WOW!! This thing ROCKS! Can’t believe I went this long without it. If your on the fence about getting one. I can say that the HiBoost 4K will not disappointed!!
Henry Pelt –
I did appear to boost signal but for whatever reason didn’t help cellular internet in my situation
Stephanie Greer –
Take the time to set it up correctly. I’m in a travel trailer for work and it took me a little while to get it going but with some help from customer service it works like a charm. From 1 bar to 5!
HiBoost Customer –
We are building a house a ways out of town and have spotty cell reception. This booster helped a lot! As long as we are within it’s range, we can make and receive calls just fine. Data is also much better with this up and running!
Dan in North Idaho –
We live in an area with weak signal, and when we stepped in our shop our signal to zero. We installed the Hi-Boost and we now have better signal inside the shop than outside in the yard. I am very pleased with the performance of this great product.
