4G/LTE External Magnetic Antenna - 6.5~8 dBi Loaded Coil - SMA

Modest cellular signal improvement even in the dead middle of a Cement block building with other radio interface devices. Purchased to boost cellular reception of Cradlepoint bench (test) device(s) which are sometimes located in the middle of a cement cinderblock building. Saw a modest improvement on cellular signal strength. Installed 2nd antenna in a 2023 Kia Telluride - routed cable through rear tailgate and into tire jack cubby on inside of vehicle. Magnetic mount sticks to the roof of the vehicle.

The magnetic bases are decently strong, but I wouldn’t leave these on the outside of a vehicle or trailer while driving. The cables are typical thin coax and it’s not really practical to extend them. If you already have a weak signal, these are not going to help much. These are fine if you just need to get to the other side of a solid object like a brick wall, metal screen, or cement block.

I bought these for the Orbi LBR20 to use in setting up an outdoor site survey for a property we are moving to. With them I was able to identify a tower that was about 15 miles away with a clear line of sight, on band 2, and get around ~8Mbps up/down once I had arranged the antennas correctly. Without the antennas I was still able to get link, but the Mbps was a bit lower. Most of my experience with this is anecdotal, but they seem to work for me and for $20 I wasn't expecting to see any sort of significant gains other than getting my router from 2x2 MIMO w/ builtin antennas to 4x4 MIMO w/ builtin and these antennas.

I ordered these to install onto my MoFi LTE router to bring in a signal in from the outside since the building was a tin box because it was built with sheet metal. This item was as advertised and mounted great and firm onto the side of the building. I would advise some kind of separate tougher adhesive or magnetic mount which was not expected in this purchase if you are in an area requiring a firmer grip on the building. Overall, this fit and had the correct connectors on the end to connect to my router. I would highly recommend this purchase!

I really didn't see a difference from the antenna that came with the camera.

I purchased these for use with my mobile POC radios. The one mounted on my vehicle gets very good 4g signal strength pretty much everywhere I go. These have a very good magnet on the bottom to hold them in place.

There is little to no improvement in cell signal strength and they don’t stay in the device

These antennas made my cellular internet 5x faster! They’re great. Be sure to check your cellular modem settings to make sure it is using the external antenna, mine used the internal antenna only until I went to the admin web UI printed on the bottom of the modem.
