Good luck finding those antenna leads at CC or BB. You would have to try a computer store or find a dead laptop with a mini pci network card and pull the antenna leads off that wire up the screen frame area. Most laptops have two antenna lead wires, one black and one white. The end of the lead just needs to have the center shielded section exposed out from the outer shielding about an inch. Either way, if the wire does not have the connector, you should be able to strip and solder the ends to the board if that how you Rx antenna lead is.
