Dlink DCF-660W External Antenna Modification Technical There is a socket on the PCB which can be used with a pigtail, but those who have used this for stumbling, have often found they don't last very long. Nevertheless this modification does allow the attachment of a standard 2dbi or 5dbi rubber ducky antenna, which many will have floating around the shed. Remove plastic cover, notice the metal strip, this is the internal antenna.
 First cut the pin leaving as much length as possible Then bend the metal strip back and forwards until the strip brakes off.
 A right angle reverse SMA PCB plug can be soldered directly to the remaining metal strip. Ensure the plug is centred and alinged with the cut pin.
Solder the cup pin to the centre pin of the reverse SMA Plug. Ensure that not to much heat is used as the pin may move during soldering.
Place the removed cover back and mark out a slot to be cut for the connector.
As noticed here the cover will not fit directly back due to the hight of the reverse SMA plug.
I find the best way to hold everthing in place is to fit heat shrink, the hot glue sealed heatshink offers the best results for strength. But normal heat shrink can be used.
