📡 High-Performance Eightwood GSM 3G 4G LTE Antenna - SMA Male Connector, Magnetic Base - AT&T, Verizon, Netgear Sierra Compatible - Enhance Signal Strength for 4G Router, Mobile Hotspot & Wireless Home Phone Review

Does what it should. We use it to extend signal reception beyond the aircraft's metal hangar to control a remote engine heater.

Bought two of these to connect to a Peplink Pepwave Max BR1 Mini. It only managed to get download speeds of around 25Mbps no matter where the router was placed in the house, even in the attic. I attached these antennas, took them out of the house and into a plexiglass box mounted high on the wall of the house. Almost 10 feet of cable will be greatly appreciated. The signal strength has increased and the download speed of the router is now just under 60 Mbit/s. That's an insane boost!

This was well packaged and was a good device at a good price but it didn't add any bars to my device. I'm not sure if this is the right application or not. Quite small as it is only about 4 inches tall. Has a strong magnet on the bottom that works well on metal surfaces.

Replaced stock antennas on my mofi 4500 sim4 router. Previously I couldn't use carrier aggregation because a tower was too far away (band 4 at&t lte was all I could get). Got about 9 down / 5 up. Added these little guys, reconfigured my router settings and bam! 4-5 cycles of 18 down / 12 up. To put it mildly, I'm very impressed. Sure, YMMV, but to me they're worth it and a good deal. I mount them high up on one of those plastic plant ledges that you attach to the window with suction cups. I…

I bought 2 of these for my LTE base at home. Before the installation I had -87dB, after the installation my signal dropped to -110dB and the speed dropped from 8Mbps to 0.65Mbps. After removing the antennas my speed jumped again as did my db. This was even after I placed the antennas right where I have my home base.
