One thing that I've gotten in the habit of doing is measuring the antenna length of a new Rx and writing it on the Rx for future reference if ever needed. I've been splicing antennas back together for over 20 years...you get good at it if you ever get into R/C combat. For around $10 you can get a nice little soldering iron kit from Radio shack. They also sell shrink wrap and spools of wire for less than a couple bucks that will repair countless antennas. Just take a piece of your old antenna in to match up the size, and make sure you get braided wire, not solid.
