ANT-124-95G

Important note: I use these mounted outside - toThe roof of whatever (always parked) vehicle I am in or carried with me if I am hiking out to a spot to work.Pros: I am often in a remote forest with one bar of LTE on my phone - messages had to be sent as texts, not able to get photos, certainly no able to browse the web. The Verizon MiFi alone was a bit of an improvement, but it was slow & a disappointment. These antenna really made a huge difference for me & made the MiFi a workable solution to being able to work from here - it wasn’t before.I can stream YouTube vids, I’m in that remote locale right now writing this using the Amazon app, I can check email with attachments and download documents from the cloud. I just tried to FaceTime, and it was not a problem, which was a bit of a surprise. Haven’t tried to Zoom, not sure how that would go.Magnets work for me, I don’t keep them installed permanently, I move them around depending on where I am in the forest where I am working, so I haven’t subjected them to staying on under any extreme conditions. I just put them on the roof of the vehicle I am in, don’t have to fuss much to get them to do their thing.Con: the only con for me is the connections to the MiFi ports are not at all secure. They seemed okay at first, but after a month or so, they just fall right out from the slightest movement. It’s a huge PITA, and managing the long cords is also a pain - I also realize that a lot of folks probably set this up and leave it, so my usage might be atypical since I am taking the antenna out a lot. It’s annoying they fall out so easily, but the reception I get is such a huge improvement that I would purchase it again without hesitation.

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.

UPDATE: Complete pieces of junk. After 10-15 minutes of highway driving, one fell apart (magnet and bottom sticker stayed on roof, antenna went flying, pulled over and it was dangling from the coax cable. Pushed the magnet back in and tried again in case it was a fluke and then a few minutes later, the other antenna did the same thing. Very, very poor construction. Coax shield isn't even soldered to ground magnet, it's just wedged between the plastic base and the magnet. Avoid these at all costs and get something better.Initial impression is good. Fairly good construction, signal strength at my house is as expected. Will be working at an event that is in a very poor 4G/5G coverage area this weekend so I'll know more later. But I'm hopeful, these have to be better than the two paddle antennas that I've got now.

I had bad reception without 4g. These antennas are easy to use and do boost the signal. They work best near a window.

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.
