I've had no problems with a traxxas reciever that I had the same problem with. I got a new antena wire from the hobbyshop, cut it to origanal length of the traxxas wire and just cut the rest of the stock wire about an inch out from the receiver,stripped the insulation and twisted the wires together and was very generious with the electrical tape.Since your reciever is enclosed in a plastic case,you really dont have to worry about the wire grounding out on metal.Has been like that for a few years now with no problems.I think the wire cost me under $2.00.Do it,it will work.Just make sure you get the length right.
