Pack of 2 RF RG316 Pigtail SMA Female Antenna Connector to Straight MMCX Male no Angle Coaxial Cable Adapter (4 inches (10 cm))

I have purchased multiples of these in several lengths and they've all been well made and work well. They are standard SMA female for the antenna connection. If you want to connect an antenna having an RP-SMA male connector (the "RP" stands for "Reverse Polarity", which means that the male does not have the center pin), such as those for DJI Air Units, just get an SMA male to RP-SMA female adapter. The SMA male end will screw onto this SMA to MMCX coaxial cable adapter and the DJI antenna will properly connect to the RP-SMA female end of that adapter - I've used this approach many time. However, to avoid the adapter, use some other quality antenna, such as a Luminier Axis 2. Keep in mind that DJI standardizes on LHCP antennas, so do the same on your drone. Of course, you can use RHCP antennas if you're going to change your goggle antennas to RHCP also.

Work good and a good price.

Just what I needed and it works great
