Quick Tips About Using U,FL/MHF4
Connect
Caring for your U,FL/MHF4 connector is all about keeping that shiny electrical contact
pristine and contacting! Grime, oxidation, and mountain dew will increase the impedance
to/from the antenna and will reduce range, Bent contacts won't let any of the electric
pixies through at all and those "it works if I hold it just right" problems are definitely the
worst to debug!
1, Inspect the antenna receptacles on the module; don't use if deformed or damaged,

2, If possible, acquire or 3D print an installation tool, If using a tool; follow the instructions found with the tool,
3, For manual installation, align the connectors so they are perpendicular,Attempting to
engage connectors at an angle damages both connectors
4, Press the antenna wire connector straight down onto the module receptacle, You should hear an audible click and mechanical snap when a proper connection is made

When connecting the parts of the U,FL/MHF4, first make sure your finger is relatively clean, To avoid putting pressure on the connection, pinch the cable one or two cm from the end and try to align it so that the female connector rests evenly across the surface of the male connector, You can then lightly put your finger on top of the stacked connectors
if it feels like your elementary school's old see-saw then try again, you want this to be stable, Also be sure that the two connectors are centered on one another left-to-right and up-to-down when you look at the connector from above the board

If everything is good to go, use the very center of your finger to press firmly down - you'll feel a satisfying "lock sensation" as the datasheet puts it! (P,S I had to move my finger off to the side so that you could see the connector in there, but you should really make an effort to push down right in the center of the connector)
Note
MHF4 connector is a tough nut to crack, especially for first-time users, It has to be dead center and 90 degrees straight down to be pushed in with a tiny bit of force, Easy does it,
Yes, it's a bit scary (just like first time riding a bicycle,)
Do not ever think to try using a slightly tilted angle to wiggle it in, That will probably hurt the connector alignment itself
WARNING, Don't pull the MHF4 connector out once installed, That part is even harder (90 degrees is the golden rule) and can potentially damage the socket on the motherboard

What can I say, they connected as they should and they work fine. Good signal and pretty good speed. I'm happy and would get them again.

While the minuscule snap attachments are delicate by design, the instructions included with the listing (align @ 90 degrees, then press straight down) were invaluable. I destroyed my original antenna trying to reattach to a new wireless card at an angle. The cables themselves are tough and rather stiff, but will bend to your will to fit. You might want to use small strips of electrical tape to hold as you spread them. Cables are quite long and best suited for a laptop. I used in a mini PC and ran them all around the perimeter of the case. Strong signal for an Intel WiFi 6 card. Very satisfied with quality!

The first one I bought did not work properly. I'm not sure what was going on, but I figured I would give it a second chance. I ordered the second one and it works great now. I am finally getting 1 gig speeds on my AX210 Intel card. The bluetooth connection is still a little underwhelming, but at least I can use my PS5 controller from a sitting distance without a dropped connection, which is all I needed. I think overall its a good value. All of the parts including the wires seemed to be strong and of good quality. I even stripped the wires on the return item to make sure.

If you are upgrading your M.2 wifi card you should probably go ahead and order these. I upgraded to an Intel AX210NGW and I was very careful disconnecting my laptop's antennas from the old card but the connectors just wouldn't fit on the new one. It seemed to me that the connectors were pressed on to the original card at the factory and there was no way to put the factory cables on the upgraded card.

Dell G7 7588 wifi card can make use of this wifi antenna, but need to modify the location of the Aux white receiver part, since the white Aux part is shorter than the Main (Black) part.

Worked as intended. I replaced the Wi-Fi card and antennas in my laptop. Very good value. This Wi-Fi card was an upgrade over my original. And this is a much more reliable version. The install requires technical knowledge but can be done. I'm an old man with poor eyesight and the antenna connectors were really hard to get connected. The cables were plenty long enough to put the antennas were I wanted them in my 17" laptop.

The two internal antennas come with wires that attach to the wireless adapter in the Dell OptiPlex Micro computer, but there are no instructions or diagrams to tell you where to attach the antenna ends without interfering with the internal components. It does work ok but one antenna is just hanging loose in the case as I couldn't find a good location to attach it. I probably would buy an external antenna kit next time instead.

This antenna worked as described for my Lenovo ThinkCentre M700 Tiny tower. Bear in mind, this antenna is dual wire which are taped together. I split them apart as I only needed one for a Bluetooth antenna. I already had a Wi-Fi antenna hooked in. I can now use my beloved Bluetooth keyboard/mouse combo. Thanks!

Funktioniert, wie in der Überschrift bereits erwähnt, fast besser wie die originale Antenne von HP. Aufgrund dessen, da die Klebe-Platinen der Antenne, welche hinter dem Display verklebt werden, etwas breiter sind als original und auch keine Löcher haben. Somit passen sie nicht an die eigentliche Stelle bei meinem Notebook.Für mich als Bastler aber kein Problem und sie trotzdem ohne Probleme verbauen können. Die erreichbaren 2400Mbit/s meiner Netzwerkkarte können somit wieder voll genutzt werden ohne nervige Unterbrechungen oder schwachem Signal.

I upgraded my laptop wifi module and needed a second antenna, replacing the original and adding the second. I recommend that you are very comfortable with the disassembly and reassembly of a laptop. Care must be taken to route the antenna coax cables properly, especially around the hinge, and mount the antenna themselves behind the display. There are two different sizes of RF connectors that I'm aware of, so ensure you get the size you need for your app.
