HiLetgo 5pcs U.FL-1 to SMA Female Pigtail Antenna Wi-Fi Coaxial Low Loss Cable 6 inch (15cm)

These were exactly what I needed and fit perfectly on to my esp32 boards for WiFi testing.

These antenna adapter cables work exactly as needed, with excellent build quality for the price. The connectors fit snugly at both ends - the U.FL side clicks securely onto wireless module ports while the SMA end threads smoothly with no cross-threading issues. The 6-inch length provides good flexibility for positioning antennas without excess cable to manage. I've used these on several WiFi and IoT projects, particularly with ESP8266 and similar modules. The shielding appears solid as I haven't experienced any noticeable signal interference. Getting 5 cables in the pack is convenient for multiple projects or having spares on hand, as the U.FL connectors can be delicate if you're frequently disconnecting and reconnecting. One minor note: the U.FL connector requires careful alignment when attaching - you'll feel a distinct click when properly connected. Take your time with this to avoid damaging the port. The cable is also fairly stiff, which helps durability but means you'll want to plan your routing carefully in tight enclosures. For the price point, these are reliable performers that save you from paying premium prices for essentially the same functionality.​​​​​​​​​​​​​​​​

This worked out great for adapting over to the old style of antena connection so I could run a wifi antena outside from my router to extend better reliable wifi out to my shop. If you have a newer style Netgear router with the cheaper semi permanent antena then this is for you if you break one or need to run an external antena. Works great.

I got these connectors to replace some older U.FL connectors that I had, that were not seating as positively anymore. These seat very positively, and appear to be of good quality. The only reason for the 4 star rating is that I was expecting to get more than FIVE connectors, according to the pic. The description does indicate QTY of 5, and that's how many I got, but the only image associated with this appears like you get more. Other than that, appears to be a quality connector...

Is a good price

Fits perfectly in my Lilygo tembed. Lightweight and mini design built strong to last. And comes with washers and lock washers and nuts to mount to your case mount. Great way to add bigger antenna externally

Recently picked up a used green mountain grill, previous owner somehow broke the wire on the motherboard for the WiFi, i bought this to replace it and it worked perfectly!! My new to me smoker now has WiFi!

This is actually a U.FL to RP SMA not U.FL to SMA adapter. I unfortunately needed SMA (GPS) not RP SMA (WiFi). It didn't work for me, but otherwise, the quality seems good.

These did NOT fit my Orange Pi project. The quality looks quite good, but I did not realize that I require IPX4 (MHF4) size which are much smaller. Just a heads up to other buyers. These do not fit the OP5 plus WiFi board.
