11dBi High Gain 4G LTE 5G Waterproof Dual Polarized MIMO Antenna with Dual 5 Meter Cable SMA/TS9 Connector for Netgear Nighthawk M6/M6 Pro, M5/MR5100, M1/MR1100, MiFi Mobile Hotspot Router, Eifagur

This 2x2MIMO antenna gave my Concord 4 alarm system new life. We are surrounded by hills and have no cell phone reception. Our alarm system requires a cellular signal to communicate to the monitoring company. WiFi nor Ethernet are not an option with our older alarm system. On top of that, the alarm company had been warning me for months that the system was not reporting status regularly, and suggested upgrading the alarm for $4800.After much on-line reading, I determined that the alarm's cellular module (in the attic) has two antennas using 2x2 MIMO. I did need to purchase different pigtail cable adapters (MMCX Male to SMA Female Coaxial Cable) which connected to the alarm's cellular board (see photo). I mounted the antenna outside facing towards the closest tower (1 mile away). Once I restored power to the alarm, the cellular board connected immediately, something I had not seen for months. I'm thrilled to have postponed replacing the alarm system.Please note that there are a wide variety of alarm systems and corresponding cellular communication modules. Mine just happened to have two small antenna's that seemed to imply that it was using 2x2 MIMO. This antenna is working great for me, but your system may have different antenna requirements.

I upgraded my 4G LTE PTZ security camera by adding a directional antenna, and the improvement has been incredible. Using the OpenSignal app, I was able to properly aim the antenna toward the nearest cell tower, which made a huge difference in signal strength.With the stock stick antennas, I couldn’t reliably control the camera or view the live feed. Now, both work flawlessly—I can move the camera and stream video in real time without issues. This upgrade completely transformed the performance of my setup.

I am trained in antenna theory and have built a long wire antenna that we actually talked to ourselves around the world on a High Frequency radio. Also built a long wire antenna to pick up U.S. AM radio stations from Honduras.Had one of those omnidirectional antennas and often lost signal. Purchased this and installed it. Now I have internet faster than my cable modem at a different house.Took a long time to install. I brought the modem connected to the antenna and walked all over my roof to find the best signal. Most of the time it was less than 2 bars. Found one location on the front of the house, below the roof that reliably has 3-4 bars. Temporarily hung the antenna there and tested it out. My internet was lightning fast compared to the omnidirectional antennas. mounted it there and ran the cables through the wall and my internet has been great for two months.There is a high voltage power line about 1000 ft from my house in the direction of the best cell tower. the higher I raised the antenna, the worse the signal got. For me, there is about a 4Sqft area where this works excellent. Luckily, that spot is convenient to run the cables inside and connect my modem to power.Mine was a very difficult install. Most should be quite a bit easier. Try a location that makes the install easy. If you get 3 bars. hook things up there. If not, grab your modem, hook it up to the antenna and try different locations until you find one that makes the install easy and gets you a good signal. Don't stress about getting 5 bars. Three is enough for fast internet.

This antenna really does work! I have it connected to my Netgear LB2120 4G LTE modem which uses a TS9 connector for the optional external antennas. There is certainly a signal quality improvement, even without going through the detail statistics. Without the antenna, I get around 3 bars for signal quality on the modem indicator lights, while with the antenna, I get all 5 bars. To really make sure that I wasn't just testing a fluke, I pointed the antenna to the floor and I get 0 bars, I then pointed it outside my window and I got 4 to 5 bars. This tells me that the external antenna is definitely working. You can see my attached picture showing the difference in signal statistics before and after the antenna is installed.However, to really get the most out of this antenna, you have to mount it right and point it at the nearest cell tower to your location. This is unlike an omnidirectional antenna that gets a signal from all directions, but rather a directional antenna where you have to point it at the right spot to get the best signal. You can think of an omnidirection antenna as a regular light bulb and a directional antenna as a spotlight.This is a great antenna and really helps with improving the quality of communication for my relatives who live in an area which is further away from cell towers that results in a weaker signal strength which was a problem especially during emergencies in current times with the pandemic when meeting physically is restricted.

Using this with a Mofi4500 on AT&T on the west coast. With the basic Mofi antennas, Was always under 10mbps. Using it with our RV, mounted on a 16 foot fiberglass pole. When aimed at a nearby cell tower, I'm getting sometimes over 50mbps and routinely over 20. Excellent speed improvement. The downside is that this thing is like a sail in the wind. If they made it smaller, I'd buy 2.

Didn’t work for us and tried it on the third story roof. Made internet even slower.

We live in the sticks, and had to use LTE internet for our house. Signal was terrible, so we bought this in hopes to fix it. We didn’t even use it how you should. (Mount on roof/pole)We placed it our window and saw good enough gains that we never mounted while we were using it. Used it for over a year with no issues, until the local ISP pushed to our area.Recommend if you have poor signal, and a good open area to use antenna properly.

Before I installed this my speeds were all over the place because of the hills around my place blocking the nearest cell tower. After getting this mounted and pointed in the right direction the connection stabilized completely and I can actually rely on it now. The physical install is a little awkward because of the size so having an extra pair of hands definitely helps.

not sure it really improved my signal. I have tried many location. Moved it a few inches, did speed test. Still in testing.
