Sanwa 451R receiver wire

[Dkfream]

Hi just after a little bit of advice if possible, my receiver wire has been chewed up at the end and most of the exposed part at the end has snapped off, I have cut back some of the coaxial to expose the inner grey wire again but it is now about an inch shorter, have tested and all seems to be working ok but will this cause interference or range issues, any advice will be helpful as I really don't want to shell out another £70 on a new one if I don't need to
Cheers
