There may be times when you have an extender cable with two different types of connections on the end of it that require an FME female to SMA female adapter. FME female connections are great for low-loss cable connections that work best with external cables and offer more weather resistance. SMA female connectors are typically smaller, work with millimeter-wave applications, and connect well to internal antennas. To ensure that your cable has the same connection options on both sides, consider attaching an FME female to SMA female adapter as a simple add-on rather than buying a whole new cable.
