Proxicast Vandal Resistant 4x4 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-M44)

Great antenna. Easy to install with bracket, and purchased the 4 mimo extensions. Be sure to buy the correct female to male connectors.

Was everything I expected and more! Saved the day for sure!

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 purchased this external external mimo antenna with hopes of boosting my 4/5G signal and after testing and moving to various locations did not see any significant improvement in signal. For an antenna thats fairly expensive I would have thought it would have produced better results

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?
