Radio Controlled Jet Ski Antenna and PVC Tube?? EASY 10 POINTS!!?

I have a rc jet ski that I got 6 months ago and I have lost the antenna for the remote control. Its just one of those silver antennas that screws in and it extends. Can I just go to like radio shack and get another one? Will it work? Also on the boat there is a wire on the back and it said to put it through the pvc tube so it stands up right but it never came with one. What do I use for that? Thanks

I’m sure they have replacement parts on the net, and look at Radioshack, they might have something. For the antenna on the back, use electrical shrink tubing. It slips right over and once you heat it up it will shrink to the wire, thus making it stand straight.
