Aerial for Futaba R603FS 2.4GHz Rx
 

The aerial on my receiver is damaged and needs to be replaced. I have asked my fav model shop to look into it but I wanted to ask on here also. The wire is a coaxial type and insulated in what feels like grey PTFE or Teflon inulation. I think the part number for it is HSP79452.

Has anyone ever had to replace their aerial on one of these?

Thanks
Neil
