Review: Immediate 10 dB gain in signal strength - 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.
Review: 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.

## Questions & Answers

**Q: Would this antena boost a wifi signal outdoors so I can provide a wifi signal for a wireless security camera?**
A: This (ANT-121-002) antenna is tuned for 3G/4G cellular frequencies.  The same antenna tuned for 2.4 & 5.8 GHz WiFi is ASIN B01N4929VN (ANT-131-002)  https://www.amazon.com/Vandal-Resistant-Profile-Omni-Directional-Antenna/dp/B01N4929VN

You could install that antenna outdoors and connect it to a WiFi router or Access Point so your WiFi camera could connect.

**Q: what would this plug into?**
A: From Proxicast:This antenna is designed to connect to cellular modems and routers which have SMA Female jacks for external antennas.

**Q: Will it work with Mofi4500?**
A: Yes.

**Q: Any successfull installations onto a commerical flat roof building with mast-mount?  Photos?**
A: Unfortunately customers rarely send us photos of their installation but there should be no issue with what you want to do.  The L-bracket that comes with this antenna is intended for wall mounting, so you will have to come up with your own method for mast mounting - perhaps a pipe clamp around the long arm of the bracket.  There are also some security camera mounts for pipe mounting that might work.

### ⭐⭐⭐ No significant improvement in signal.
*by W***. on January 4, 2026*

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
