Proxicast 6.5~8 dBi Gain External Magnetic Loaded Coil 4G Antenna AT&T Nighthawk M5 / MR5100, M1 / MR1100, Velocity 2, Verizon Jetpack 8800L & Others MiFi Hotspots w/ TS9 Connectors (ANT-124-TS9-2PK)

So this is not a booster. It does not clean up your cellular signal, that is a different device. What these antennas do is help bring in the cellular signal to your mifi device if you are in a remote area. It can make the difference between having a signal or not. We travel in an RV and often camp in remote areas. These attach magnetically. Since the outside of our RV is not metal, we glued little metal pads to our roof to stick the antennas to. We ran the cords under the seal around one of our windows. The magnets are strong. They have not slipped or blown off during storms. I take them down while traveling. They attach to your mifi device via two TS9 connectors that fit nicely, not too loose but tight enough to stay connected. Before ordering make sure your mifi device has antenna ports since not all do. Your ports might be covered with small rubber plugs, they are easy to overlook. These are a great deal for the price and benefit as long as you understand that this is an antenna, not a booster. For the best signal, you could get both an antenna AND a booster.

I was skeptical at first but this antenna performed well for my purpose. I deployed to Iraq without a means of cheap Wi-Fi and was able to order this to the coalition forces base I am currently residing. The antenna hookups matched my Netgear M2 Wi-Fi puck, and the 10ft cable was long enough for me to put the antennas on top of my housing unit. The magnet was very strong, I’d say about 5 pounds of strength and kept these held down during dust and wind storms. Not waterproof, so I take them down when anticipating bad weather but otherwise these were great. I get great 4G service with them, and a buddy used it for 5G service which he said worked great.I would recommend this for people deploying through the CENTCOM theatre if they wanted to avoid paying the $150/month for Wi-Fi on one device only.

Easy install, cable length is good, seems durable - however, while testing these on a Netgear LM1200, despite of multiple locations, different heights, testing one/the other/both:TX Power was up 33%Quality was up 15%Bandwidth speeds were half. :(

So I purchased these Proxicast 6.5-8 dbi Gain Antennas to use with my Netgear Nighthawk MR1100 LTE Hotspot. I'm in a very rural East Alabama town and there isn't fiber internet, cable internet, DSL, etc. Our options are Satellite or Hotspots. Anyways. My Netgear device doesn't do very well without external Antennas so I purchased these and they definitely help the signal and speeds.(40 Mbps down and 12 Mbps up average). My issue is with the Ts9 connectors. Specifically the copper coaxial strand in the center that slides in and completes the connection. They're very fragile and break easily so be careful when you're connecting to your device. Other than that they work well and would purchase again.

Positives: Cheap, light, it works.Negatives: There is another product by the same manufacturer that is much more expensive and which works better, but it is heavier.Whether it works and how well it works, is for me the most important. I tested the antennas in a very poor signal situation and compared it to the no antenna results and to the more expensive antennas results. Here is what I found.The number of bars shown on my M5 didn't change at all, but the speed tests that I ran DID change.I used the ORKA speedtest app on my iPhone 12 pro max with my phone wirelessly connected to my M5 using the 5G wifi and my phone close to the M5 so as not to lose throughput because of distance. I also put my phone in airplane mode, because when I use the M5 with cellular service enabled, I get disastrous results! Averaging over a small number of trials, here are the results that I obtained:M5 without antennasDownload: 3.87Mbps, Upload 0.24Mbps, Ping: 42ms, Loss: 14%M5 WITH these antennas (proxicast ANT-124-TSç-2PK)Download: 6.98Mbps, Upload: 0.52Mbps, Ping: 108ms, Loss: 18%M5 with other antennas (proxicastProxicast 8 dBi High Gain External Magnetic Antenna Compatible with AT&T Nighthawk M5, ...)Download: 8.44Mbps, Upload: 0.51Mbps, Ping: 61.5ms, Loss: 0%The VERY poor signal case is important to me, but the antennas are important to me, and hence my test in a signal-deprived Location. In the tested scenario, the antennas made a very real difference to the usability of the connection. The more expensive antennas, nearly 4x more expensive, provided better results, and are more physically stable, but they are also heavier. These antennas easily fall over, whereas their expensive and heavier big brother does not. I decided to keep both pairs because sometimes the lightness of this pair will make a difference. When I want to be really sure, I will use the more expensive ones, and the cost of lugging around heavy antennas.

I use these antennas with a Verizon hotspot while livestreaming sports games. I was looking to improve my connection reliability in fringe areas. These improved my connectivity immensely. In one location, I had historically seen 20% packet drops on my stream, but after connecting these (same location), the packet drops went to zero. (This is over a two hour stream each time.). I would highly recommend.

I compared signal bars and speed tests with and without the antennas installed.There was no performance gain with the Proxicast Antennas on two different cell towers in my area.These Proxicast Antennas didn't work as expected and were returned.Take these findings with a grain of salt, because the NETGEAR LB1120 might not be a device that works well with this type of dual antenna array.I don't own any other devices that might work okay with these Proxicast antennas. Due to the TS9 type connectors, I was unable to test the SWR of these antennas on my NanoVNA.
