Proxicast6.5~8 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)

I've set up the antennas according to the manufacturer's instructions - ~2 feet apart at a location with unobstructed view of the sky.* There was an immediate and consistent 5-6 dBm boost to the signal strength (RSRP) and 4-5 dBm boost to the LTE signal quality (RSRQ). This is quite good for a passive pair of antennae, and has been serving my purpose.* Download speeds have increased from ~20Mb/s to ~30Mb/s and Upload speeds from ~5Mb/s to ~10Mb/s on the Verizon network. Note that the Netgear M1-MR1100 is not optimized for the Verizon network and is missing a few LTE bands used by them, and despite that I observed a noticeable improvement to the network bandwidth.* The TS9 connectors do not fit very snugly and would not go all the way into the antenna ports, but the connection would be strong enough that a tug at the cable would not make them come off.

I bought these antennas because I have a Netgear LM1200 inside my network cabinet. The built in antenna does not work that great when it's inside the metal cabinet. I bought these antennas and added it on top of the cabinet so that it can get a better signal outside of the cabinet. The included cables are really long but are were great in my case since I used about 6-7feet of it running it from on top of the cabinet through the bottom opening. I am able to get about 90/90mbps full bars LTE with these antennas which is not bad considering the cabinet is inside my garage and not in a wide open area.

Used with a Mifi 8800L Jetpack. in a rural environment. Usually obtained 1 to 2 bars. Antenna installation now provides 3 bars most of the time.

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.

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.

For the price, it can't be beat. I didn't want to buy a $300 directional Antenna so I tried these. Speedtest.org usually gave me about 2-4 Mbps without antennas (sometimes less than 1Mbps). I couldn't stream at all in the countryside. Plugged these in and played around with positions in the house and immediately got 15Mbps average. Eventually put on Window seal inside and average 20Mbps. Opened the window today (2 weeks after purchase) and jumped to 34Mbps Average. Streaming is strong with this on multiple devices. I logged in to see if they are safe to put outside and the Q&A section said yes. so I'm trying it now. No improvement from sitting outside or inside with open window but with winter coming. I will leave them just sitting on a window seal outside. This is a much better option than paying for expensive starlink ( gonna as for a refund since it's been a year of waiting) or expensive permanent mount directional antennas.

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.

Great antenna for improving cell signal
