Proxicast 4x4 MIMO 5G Antenna - Vandal Resistant Low Profile Omnidirectional Through-Hole Mount - 6 ft Coax - Black - Compatible with Cisco, Cradlepoint, Digi, MoFi & Others (ANT-121-T44-B-06)

Had T-mobile router moved to enclosed IT room, centered within the building. Service degraded to average 100Mbps. After adding the external antenna, service has been solid 600Mbps average. Peaking at 667Mbps.I was surprised by the performance given the tiny size of the unit. Signal shown on router is full (full bars). Before I had an average of 3 bars.No issues now during rain either.

Did not make any difference on my signal

Having good cellular service is a must when you have computers and car key programming equipment. I bought this antenna to hook to my GLinet cellular router. My speeds are consistently faster than when using the antennas shipped with it (more than doubled). I paired it with an outdoor antenna for Wi-Fi as well and now when I am working on a customer vehicle my equipment can reliably ask for permission from the vehicle manufacturer or report the vin numbers correctly so I don't get held up or have to use my hotspot on my phone.

Since locating to my current spot, I have had almost no 5G service reception... My previous spot I was routinely getting 400-500gigs down and 30up. I spent months fighting with the service provider about the 5G desert I was in and they did confirm signal was weak, but present...I upgraded my Modem/Router with the vendor to get the external antenna option and then ordered this 4x4 MIMO antenna hoping for a miracle.After connecting and mounting the antenna outside I did a SpeedTest using the Internal antenna and wasn't able to connect to any servers and errored out - like always.Swapped signal from the Internal to the new External antennas and performed the SpeedTest (see photo) and holy moly! I have 5G Internet again!Turned off the Starlink to save $100/month to use the 5G.This thing is tiny, but powerful - well worth the investment!

I was extremely pumped to get a new router with external ports and very optimistic to get this antenna and hopefully pick up some extra signal. I even built a bracket to hold it outside of my shops main door. I tested it without the bracket and didn’t necessarily get any better results than the internal antenna and after mounting it I did gain one bar of service for roughly 10 minutes but needless to say it hasn’t worked for me. I’ll continue to stay optimistic as there is a new tower being constructed near by so maybe that will chance a thing. The overall quality though is extremely nice.

…not sure if all of that work was worth it considering just one bar of extra signal and only 12 or so feet of cable by the time it got fished outside of the wall.More length would have helped…and frankly…the cost of putting it up seems a bit much considering how little we got in return.They talked this up pretty big. I have to say…Definitely underwhelmed.

It did not work for me.
