The K0R41 External CC1101 Antenna for Flipper Zero is a game-changer if you're looking to extend your Flipper Zero’s range and performance. This accessory is super easy to attach to the SubGhz GPIO board, giving you better signal strength for all your wireless interactions. Whether you're exploring SubGhz frequencies or just need that extra reach, this antenna works wonders for improving range and stability.The build quality is solid, and installation is a breeze. It fits seamlessly with the Flipper Zero, and you can immediately notice the improved functionality. If you're serious about getting the most out of your Flipper Zero, the K0R41 antenna is a must-have upgrade!

It works great the 3d case for the circuit board is very fragile but works like it's supposed to

I’m not that kind of guy who throws bad reviews, but I feel frustrated with this purchase. As soon as it arrived, I tested it on my Flipper Zero, but unfortunately, it didn’t work. I tried checking the internal settings to see if the issue was on my end, but it really didn’t work. I completely wasted my money.

Feels a bit flimsy, but works overall. Pins are long enough to hold it in place even with a silicone case. Antenna is OK, tho wish it was removable in the event you wanted to attach a longer one.

This works great, I can definitely see a performance improvement with it as opposed to without it, in my case, sending a signal through some walls to the other side of your house I wouldn’t be able to do that without this intense extension. Great add-on until Flipper adds a better built-in antenna.

3D print quality wasn't the best, this package took like a week to get here. Got sent back, not the sellers fault. 3 stars because the Antenna was bent and the shell was kinda open.

So far so good. Not sure why people are complaining about the case. Yeah, it's 3D printed- so what? If it didn't come with one I would just have to print it myself and this saved me time.IMPORTANT:If you are using Momentum firmware, in addition to enabling 5v in the GPIO settings, you will also need to go to MTNM->Protocols->GPIO Pins and set CC1101 SPI to "Default 4" instead of "Extra 7". Once you do this you should be able to select External in the Sub-Ghz settings. It won't recognize the External until you do this- from experience.

The CC1101 is removable so it can be used in other projects. I like that :)I ended up needed it for a 315 mhz device and found a good antenna for that frequency on digikey for $15. Haven't used the 433 mhz option yet. I was able to test it with the new antenna + device in my neighborhood. Without direct line of sight of my receiver, i found it to work up to 62 meters away (~200 feet). The remote the receiver came with only works up to about 30 meters (100 ft) away.
