It didn't fit my x4r-sb connectors. looks like there are two versions of the reviever. Mine has smaller antenna connectors and there are another version of spare antennas... You can see a difference on the photo. The bottom one is a connector of the antenna of this lot and the upper one is an original from my x4rsb... So check your version twice!
