Funciona para lo que necesitaba

I purchased these for a relative's US Cellular home phone device (D-Link DWR-920V), who was having poor cell reception and inconsistent call quality. I was hoping to see a little improvement in reception using these and avoid running new wire (changing the device location).Pros:- The hook-up was easy ...just remove original antennas, screw on new ones.- Fit was good. Build quality appears good- They are larger & more robust than the original D-Link antennas.- Price was reasonable- Shipping was quickCons:- They didn't seem to improve reception at all over the smaller original antennas, despite orientation or direction. We were getting 2-bars of reception and I was hoping to get 3, or at least more reliable phone capability. Didn't seem to make a difference. We moved the unit around and could not see an improvement using these. Maybe there are others out there which would work better?? So we stuck with the originals.Ultimately the solution was to move the D-link receiver to a new location at the upstairs window more in the line-of-sight to the direction of the tower (a few miles away). That got us a consistent 3-bars and sometimes 4 with the original antennas. And consistent telephone service. It required running more wire to the phone, but that has been the best solution. I'm going to keep the antennas for another possible future application. Cheers!Hope this helps.

For my application using a Victron Energy GL520 I did not notice any improvement in the LTE signal and in fact it was worse. So it could be a mismatch or these just don't perform. They were too cheap for me to return so I may use them on an internal router.

Once I installed this Bingfu Antenna onto my Orbi Cellular router at our camp ground it increase upload and download speeds well enough to allow multiple devices to be connected and allow streaming that wasn't previously working without the Antenna. Please make sure to use this antenna for the 4G LTE connection on your Orbi or you will not receive the positive results you desire. (personal experience!) I recommend this Bingfu 4G LTE Antenna to anyone wanting to improve download/upload speeds with your cellular 4G router

When in connected these antennas my router went offline and wouldn't connect to any LTE bands. Remove them and return to factory antennas and the router connects. Avoid these knock off antennas that will degrade your connection

I have an Earthlink modem that was broadcasting a weak signal that my home security camera. I bought these antennas and immediately my camera worked. Absolutely recommended for this type of home modem weak signal issues.
