External CC1101 Antenna for Flipper Zero - SubGhz GPIO Board Attachment Accessory Black K0R41-CCV2

Works well. I’m just an idiot.

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!

1) If using this device with a Flipper Zero, it will not work with the SubGHz App. The device requires the 5v GPIO pin be turned ON so it can get power (pic 1). However, when the SubGHz App is opened and External antenna is selected (pic 2), the 5v GPIO pin turns itself OFF (pic 3) and the device no longer gets power.2) No instructions are provided with the product, so you have to rely on dubious Internet searches that turn up conflicting information. No solution has turned up about the 5 volt power problem, either.

This is well built, the pins are long enough to fit snug against the flipper and not go anywhere but if bumped it can pop out. The GPIO Pins are solid and dont bend. The housing is a snap apart housing that appears to be 3d printed and does the job. The only thing that i would want to improve would to have the pins a tiny bit longer so it can stay snug with the silicone case on it. Or if someone designed a silicone case to support this being left on to keep it down. If you have the silicone case this thing will pop off if you throw it in a bag or pocket, so be careful. Definately worth the buy- Unfortunately i havent had much time to play with it other than annoy tesla owners.

It's bulky but it handles business. Mine fell on my kitchen floor, and literally vanished. So I'm buying another.Pretty good signal range for activities.

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.

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.

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.
