4G LTE 9dBi SMA Male Cellular Universal Wide Band Omni Directional Antenna Compatible with 4G LTE Wireless Router Mobile Hotspot Wireless Home Phone HCO Spartan Trail Camera（2-Pack）, Eifagur

Works perfectly

these work amazing for an off brand! my bf broke one of his so i ordered these for replacement! very great product and worth the money!!

I couldn't really tell if they made a big difference. They worked as well as the others - maybe better. I felt better psychologically assuming they would drop less packets or have more range and overhead. I'm sure there's a measurable improvement if negligible. No complaints. Look cool. Allow directional adjustment or at least the look and feel of it. Hah.

Worked as good as the factory antenna on my Go live Spartan If not better.

I picked these up for my GL.iNet Spitz X750 4G LTE SIM card router because I was hoping they would improve my signal and possibly give me a little better throughput than the stock antennas. They do work with the router, but in my case the results were mixed. The first thing I noticed is that they did not cause any obvious interference once connected and working. I also did see some improvement in RSSI and overall signal strength, so they were not doing nothing. The problem is that I did not see any real improvement in actual speeds compared to the stock antennas. My throughput stayed about the same, around 31 Mbps down and roughly 12 to 15 Mbps up during testing. The stranger issue I ran into was during reboot. If these antennas were attached when I restarted the router, for whatever reason it had trouble re-associating with the tower. I had to swap the stock antennas back on, reboot, let it reconnect properly, and then I could switch these back on afterward. Once the router was already associated, these antennas worked fine. So there is definitely something odd going on there, whether that is a frequency mismatch or just some compatibility quirk with my setup. For reference, I bought the SMA male version because my SIM card router uses female connectors, so physically they fit and connected without a problem. Build wise they seem fine. I just cannot say they delivered the actual performance boost I was hoping for. They are a good value an easy to install but I didn't really notice any substantial improvement. So overall, I would say these may help signal strength a little, but in my setup they did not improve real world speeds in any noticeable way. If you are expecting a dramatic upgrade over stock antennas, I would keep your expectations in check. TLDR: Tested these on my GL.iNet Spitz X750 4G LTE SIM card router. They did slightly improve signal strength, but I did not see any meaningful improvement in throughput over the stock antennas. Also had a weird issue where the router had trouble reconnecting to the tower after reboot unless I swapped back to the stock antennas first.

Critters break off the factory versions and these are quick cheap replacements that work as good as the factory originals

Work great with my spartan cameras

did not fit
