    • For other carriers, confirm which frequency your provider is using and make sure this amplifier supports it before purchasing! Contact us if you need any assistance.

IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

The SureCall Fusion4Home is an all-carrier cell phone signal booster designed for home and small office use. These boosters produce enhanced voice, text and 4G LTE data signal where signal is weak due to distance from tower, topography or building materials. Fully configurable for all indoor environments, Fusion4Home signal boosters ensure enhanced call clarity for simultaneous users.

How it works: The outside antenna picks up the cellular signal and sends it through the first cable to the amplifier. The signal is then boosted and sent through the second cable to the inside antenna, which rebroadcasts the boosted signal. All of your modems/phones within range of the inside antenna can benefit from the boosted signal wirelessly.

*Many factors will influence the actual coverage area you will see from a repeater, including layout/floorplan, construction, and original un-amplified signal strength. Depending on your situation, you may see more or less coverage than the estimates listed here. It is not possible to guarantee coverage area.

Installation notes:

  • In order for your system to function properly, you must maintain adequate separation between the outside and inside antennas (if the antennas are too close together, there will be oscillation/feedback between the antennas and the amplifier will shut down). This amplifier requires approximately 30' of separation between the outside and inside antennas. Separation can be horizontal or vertical.
  • If you cannot achieve adequate separation to eliminate oscillation, you can turn down the gain on the amplifier, but that will result in a smaller coverage area from the amplifier.
  • The Yagi antenna must be aimed directly at the cell tower - if it is not aimed properly or if there are too many obstructions between it and the cell tower, it will not be effective. If you can't accurately aim the antenna, we recommend buying the kit with the omni antenna instead.

I now have great internet in a area where my only option was satellite... I would recommend the directional antenna if you live in rural areas and only get partial signal on your phone. Order the Omni directional if you live closer to town. I ordered a yagi directional antenna and combined it with this system and it’s great 10-15mb/s down
1-3mb/s up...can’t complain.

My wife and I have been without cellular reception in our house for over 3 years due to the house being metal and having lots of glass as well. Cellular reception outside the house is great, just inside is the issue. Boosters can be expensive, so I didn't know which one to purhase after many reviews and research. I had been watching the surecall fusion4home model and found that it was on sale ($250) at the 5Gstore, so I took a chance. Very easy to hook up...basically plug and play as long as the antennas are far enough aprart. Left all the gains on high and it has worked great so far, we can now listen to music and watch videos as well as work from home remotely. I am extremely pleased, we will see how it holds up for the long term.

I am using this in a travel trailer with an outside wilson yagi antenna (purchased years ago), to be used once we are set-up in a campground. At our current location when unit is turned off my cell signal is -116db and with the unit turned on it is -94db - I am extremely happy with this. Using my cell phone 25 feet from the inside antenna there is no difference - still works great. I plan to take the repeater along on my sailboat and running the omni antenna up the mast, I purchased an additional 50 ft cable for this purpose. Shipping was very fast, I received this item 2 days after ordering. Overall I would say I am very satisfied, however because this item was on sale when I purchased I have to say I am extremely satisfied, the benefit to cost ratio is way up there. THANKS 5Gstore for the fantastic pre-sale tech support!

Great customer service. This unit was exactly what I needed

We have been using a Wilson Sleek to improve our tethered internet service here North of the Wisconsin Dells.We decided to get an in house repeater to avoid putting the phone in the cradle to get on line.Without the Sure Call unit on Verizon we get 2 bars at best and very slow internet.With the Fusion 4 I get 4 bars on an old Samsung 3 and 5 bars on a Samsung 7.We have an all band Yagi at 35 feet aimed at a cell tower 3 miles towards the Wisconsin Dells.We also get 3 bars within a 100 ft circle around our lot.
I recommend this unit for anyone with weak 1-2 bar cell signals who need to get on more speed via their phones.

Arrived on time. Works ok some improvement on my cell service. Getting the yagi ant to see if it will boost the signal some more.

It does work very well. I was in a "dead" spot inside a construction trailer pulling in -117 dBm prior to buying the Fusion4Home 3G/4G Repeater Kit. After installing and putting the antenna 22 feet in the air, my signal improved to -86 dBm inside the trailer and that is pushing into a Cradle Point i'm distributing wifi with. It works very well for me and I am glad I made the purchase.

I had decent signal strength before using this and horrible latency (dropped packets). After installing this and testing I have a stronger more consistent connection with approximately 20-30ms less latency. Major improvement in my book.

I live in a rural area. Around the house was always spotty cell service, especially with 4g and voice calls. After installing the antenna I now have excellent voice service 3 bars on average crystal clear. The 4g data is also a 100% improvement. I really like your product.

My 3G repeater had failed in the middle of winter and I did not look forward to climbing on the icy roof to replace an antenna. I was pleased to see this kit priced at just $300. By using an N-F adapter, I was able to have this 4G repeater working with my existing indoor and outdoor antennae in under 10 minutes! And I can now receive a 4G signal, too! If it lasts as long as my last repeater (and I expect it to),I will consider this a great buy!
