TS-9 F to FME-Male External Antenna Connector pigtail adapter cable is eighteen inches long. It has a FME Male Connector on one end which serves as an exterior antenna port which can lead to an outside building or vehicle cellular / wifi antenna. On other end, it has a TS9 adapter connector which can connect to an outside antenna RF port found on most mobile devices to boost signal. Examples of such devices are cell hot spots or wi-fi routers made by Novatel, ZTE, Sierra Wireless and many other manufacturers of mobile / wifi modems including:

• AT&T Lightning.
• AT&T Mercury.
• Huawei EC168.
• Netgear Nighthawk LTE Mobile Hotspot Router.
• Netgear Zing 771s.
• Novatel Merlin PC770.
• Novatel U760.
• Ovation MC760.
• Pantech UML-175.
• Sprint Novatel Ovation U760.
• USB760 Modem Antenna Adapter Cable.
• Verizon Jetpack MiFi 6620L.
• Verizon UMW190.
• Verizon USB760 EVDO Rev A Modem.
• Virgin Mobile Broadband2Go MC760 USB Modem.

The TS9 Female plug fits right into the RF port of your cell phone, if it has an external RF port. Older phones have them, but newer cell phones typically do not have it. It can be used on a hotspot/ router/ modem type device such as Mi-Fi which usually always has an external antenna port that is used to enhance signal by connecting an exterior antenna.
