Do a site survey before buying this amplifier! If you're purchasing this to use in just one location, we strongly recommend doing a site survey first to determine whether the amplifier will help your signal and performance and to give you an idea of what kind of results you can expect from it. Start here: Will an Antenna/Amplifier Help Me?

If your signal is extremely poor (-108db or worse), an amplifier may not help you. There must be some usable signal available for the amplifier to boost for it to be effective.

Now there’s a mobile signal booster for those using Verizon Wireless® LTE devices – the Sleek 4G-V from Wilson Electronics. This powerful signal booster helps you stay connected by providing a strong reliable signal in weak-signal areas, reducing lost connections and speeding data rates. It boosts both voice and data communication – making it perfect for phones and wireless hotspots like the Verizon JetPack™.

The Sleek 4G-V works with all devices on most conventional 2G and 3G networks as well as the Verizon Wireless 4G LTE network. Wilson signal boosters feature cell site protection technologies refined over more than a decade of research and development. Optional indoor accessory kit (sold separately) allows use at home or in the office. FCC type accepted.

How it works: The magnetic mount antenna picks up the cellular signal and sends it through the cable to the cradle amplifier. The signal is then boosted and pushed out to the phone or device sitting in the cradle.

Installation notes:

  • The magnetic mount antenna MUST be connected to something magnetic or it will not work! If you're using the Sleek in a car/truck, you can simply stick it on the roof of the vehicle. For home use, we recommend buying the indoor accessory kit (sold separately), which includes a window mount that provides a magnetic base for the antenna.
  • Your phone or hotspot must be in the cradle to benefit from the signal boost.

We have had this booster now for a couple of weeks. It has done what it is suppose to do. We are gate guarding in the oil patch of South Texas and was having some issues receiving a good Verizon signal. Works great. We are able to use our Laptops with the data and also able to make phone calls. But we have to switch from one devise to the other, since it is only good for one or the other.

Works regrets...

Improved my signal strength by 14-16 dB both on a Novatel 4620L and a Pantech USM-290. Signal went from 2 bars to 4. The antenna that comes with it worked as well as the 13" antenna that I had here already so I stuck with it. I tried their suction-cup window mount but got a better signal by sticking the magnetic base to a 2-1/2" diameter steel part I had and putting it on top of a 6' high book shelf. You could use a can of mushrooms and get the same result. If using indoors like me, you need at least a 2A USB power supply for proper operation.

I live in a rural area where I cannot connect via DSL, Cable or Fiber. My best option was a Novatel 4620LE Mifi setup. I need to use the Verizon footprint. Without the Wilson (on a good day) I was getting 4GLTE 2 bars and the RSSI was in the neighborhood of -112dBm (not good). Using the Sleek, I am pretty consistently getting 4 bars with around -90dBm, still not the greatest but my speeds are generally around the 17mbps down and 3mbps up. A far cry from where I was before 4G. Very happy with the product. I know that the review says to focus on the product but I cannot say enough positive things about 3GStore support. They worked with me during the pre-sales and post sales process... they are my first choice for products of this type. They truly want their customers to be satisfied.

We bought this to go along with our 3047 3g4g full-band-outdoor-omni-antenna and low loss cable assembly. We love the results and found even South of Quartzsite in the desert we were getting 4g service on our Verizon Mifi card when others were not getting any service. We're using this setup in our Winnebago Adventurer and would highly recommend it.

Using a Verizon MIFI, without Sleek, 2 bars, -113 db, with Sleek, using the included antenna, 3 bars -63db in the outskirts of Yuma, AZ. Great product, great service from the 3G Store.

I do alot of traveling in various parts of the state, North Dakota is a rural areas, sparsly populated, and my calls were frequently dropped while talking. Since using this booster , I only lose about 10 % of my calls. The price is waht my installer wanted for the labor. It is movable from vehicle to vehicle and My wife likes it to use with the Verizon WIFI for doiing her computer work while I drive. I am well pleased.. The shipment was fast and straight foward, Good service and inexpensive, just what I value most.

Great little device! Works as advertised. It gave a tremendous speed boost to my Verizon 4G Motorola Droid M, which has no antenna capability. It did not do much for my 4510 4G hotspot, but that has an antenna, and I have a cell tower close by. I did not expect any boost there. I got it on sale. It was a good buy.
