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

Works great! Need companion connectors for most applications.
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.

No significant improvement in signal.
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

Proxicast 2x2 MIMO Omni-Directional Screw Mount Antenna
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?
