Vandal Resistant 2x2 MIMO Low Profile 4G/5G Omni-Directional Screw Mount Antenna - 10 ft Coax Leads - for Cisco, Cradlepoint, Digi, Pepwave, Sierra Wireless and Others (ANT-121-M22)

First, I am using this to provide an external antenna for my MoFI 4G cellular router. I use the router on the road, primarily for data communication, both when I am parked while camping and while I am actually on the road. The easiest, fastest way to boost cellular voice communication is by using WiFi calling, connected to such a device, since there is no way to add an external antenna to most cell phones, to improve signal strength. Where I had 2 bars, I now have 4. I have not tested this driving across the boondocks in Utah, Wyoming, or either of the Dakotas. That test will come, this Fall. Because it is also intended for MiMo devices (Multiple Input, Multiple Output), it can also take advantage of multiple towers in range as well as multiple channels fo input signal, as long as the device connected to it can also take advantage. That is why I chose it to pair with my MoFi device. Second, I wanted to mount it using existing holes in my RAM1500 roof. Since I have an after market radio in the truck and I do not use any of RAM’s built in GPS or Vehicle support links, I removed the existing GPS antenna wart and installed the Proxicast 2x2 Low Profile 4G/5G Omni-Directional screw-mount antenna in its place. I had to use a large washer on the inside of the truck, but there was plenty of room between the headliner and the roof. The antenna also includes a self adhesive gasket, to seal between the antenna and the roof. Be sure to clean the roof thoroughly before installing. Third, the delivery was fast. Although I am a Prime member, I didn’t pay extra for special shipping, so I had to wait for a 2-day delivery. (Sorry, I can’t help being a little sarcastic about how impatient people have become, expecting instant gratification). Everything I needed was in the box, especially since the antenna is equipped with SMA male connectors (standard screw-on for most systems, including mine). No, I am not including any logs, measurements, channel tests, or other technical information. I am reporting the information that people who do not work for the telecommunications industry would want to know, without being bored to tears by reams of data. It works better than the same device with an indoor antenna and it is better enough to justify the cost. I will be ordering more to install on other family vehicles.

I use a Netgear MR1100 Mobile Hotspot Router. In some areas of poor cellular reception, I wanted an external antenna. The Proxicast ANT-121-M22 appears to be well made and it does improve cellular reception. My only issue is that the hardware nut used to secure the screw mount did not meet my expectation. My thought is that the supplied nut and lockwasher are cut to facilitate installation over the antenna cable. I replaced the supplied nut and lockwasher with a standard M12x1.0 nut. See the attached photo. Which nut would you choose to secure the antenna to a moving vehicle?

I used to get disconnected while playing video games in my semi truck over the road. Since I've upgraded to this new antenna my hotspot has not disconnected me once! I haven't mounted it, it's just laying on some cloth in an overhead storage compartment. I haven't been back to Georgia yet which is where the worst 4g-5g reception I've ever had is. So I don't know if it can mitigate the poor reception there. But I have high hopes given the performance increase I have thus far seen. See pic for the type of assembly that you may need to do. It's not for the faint of heart or those with fumbling fingers.

I put this up with the included mount and it reduced my coverage significantly. When I called, they told me that it requires a plane to work. So it is meant to be mounted through a roof or some large flat surface that it can use as a plane. It has the same DB or equivalence as the tiny paddles or antennas shipped with most modems. If you are looking for better signal strength or longer distance to a tower, then this is not for you.

Set this up on a vertical 4ft PVC pipe on top of a big metal garage/workshop. No internet providers in the area, and only a faint AT&T LTE connection on the street. Used a TS9 splitter to run into a Netgear LTE modem. Running two bars from AT&T with this and could probably get more if I angled the antenna towards the cellular tower. But it works fine for now. There have been a few nights of below freezing and snow/ice storms and this worked through it all.

I live in the basement and use the Huawei Pro 2 router I used to put the router adjacent to the window, which is at ground level, in order to get the best signal, and it was between 2 to 3 for the 4G and 5G After I bought this antenna and I also bought connectors, I replaced the internal antenna of the router and disconnected them completely, and connected this antenna to the motherboard of the router. I got a full signal, and the speed and ping are excellent. Knowing that I wrote a previous post saying that it did not improve anything for me, and I think that the problem was with the connectors that I bought in the past, and they were bad

Mounted atop my RV coupled with a MoFi router. Speed and signal quality didn't improve much but it was worth a shot for under $100.

I added this antenna to my Netgear LB1120 LTE modem to try to increase the signal at my aircraft maintenance shop on the outskirts of town. It really provided a good gain, I was typically 1-2 bars on the modem and very slow speeds and with this antenna I am now almost always at 4 bars (occasionally 3 for whatever reason) and the speeds came up nicely as a result. Very happy with it, made my internet solution much more usable, as I can't get DSL or cable out at the shop.
