HiLetgo 2.4G 3dBI Wireless SMA Antenna with Extension Cord for NRF24L01 CC2500

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.​​​​​​​​​​​​​​​​

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.

There's not much to say. These pigtails are exactly what you'd expect. U.fl smd connectors on one end and SMA (NOT RP-SMA) on the other. Easy to install so long as you are gentle with the U.fl connectors. They seems to work well with out introducing much signal attenuation or reflection.

These work great if you're *definitely* looking for U.FL to SMA (GPS, 5G, etc) female.If you're looking for something compatible with typical "WiFi" antennas you might already own, look for RP-SMA not SMA. (Yes, RP-SMA male has a hole.) Also pay close attention to your wireless board's connector, it might not be U.FL.Thankfully I had both SMA and RP-SMA antennas lying around. I wish the product made it clear in the description, but its on me. Also odd the packaging mentioned MHF4 and RP-SMA, so I crossed it out.

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...
