The extension is provided at its ends with a RP-SMA male connector (screw on the corresponding socket of the router) and the other end with a RP-SMA female jack (for screwing the antenna). For the record, this is the fixing screw 1/4 "(7.9mm) to coaxial cable as found on most wireless routers they are detachable antenna TP-Link brand or another.
Attention some cheap routers have an antenna permanently attached to the housing and shall not use this extension. In the same vein, you can probably use this extension directly with an indoor antenna. Indeed, numerous outdoor antennas use an N connector much bigger diameter. If you want to connect an external antenna to your WiFi router, you will head more toward the purchase of a suitable extension cord as the antenna cable Type N TP-Link TL-ANT24EC12N to which you must add a RP-SMA adapter / Model N as the cord pigtail TP-Link TL-ANT24PT. But you can imagine that this solution increased the note. So to reserve only if you really need an outside antenna!
To return to the extension TP-Link TL-ANT24EC5S RP-SMA, this one is in good order. The cable is stiff but not excessively and connectors are screwed perfectly both side router antenna side. In short this extension gives me satisfaction. At advisor so if you wish for one reason or another WiFi antenna away from your router to which it is connected.
