Bingfu Fakra Z Female to SMA Female Vehicle Antenna Adapter Cable 30cm 12 inch for Car Stereo Android Head Unit GPS Navigation FM AM Radio Sirius XM Satellite Radio 4G LTE Telematics Bluetooth Module

Used this combined with a resistive load to reversibly disconnect the cellphone antenna in my car. Works nicely and doesn't damage anything so it's totally reversible.

This fits both the cellular, and GPS antenna, on a Chevy infotainment system.

I use these for CV2X (~5.9 GHz) and GPS antennas. They work great. Bingfu is my go to brand for great value RF cables and these don't disappoint.

Works

I recently bought a used GM vehicle and was never a fan of OnStar but when it came out that they were selling data I started looking for ways to block OnStar since I refuse to pay for the overpriced service.Just a heads up: for some older vehicles (for me, a 2017-2021 Bolt EV) you may need two of these and two terminators. There was a brown and purple connector coming out of the back of the center screen. Unplugging the brown caused the OnStar light to go red but it would still dial in. Unplugging both killed the service completely. The only downside is I no longer have the built in compass, but I’ll get used to it.

Perfect for blocking GM OnStar cellular antennas. All you need are 2 of these, and 2 SMA Male 50 Ohm terminators.

Exactly the part I needed.

Good quality cheap price!
