      I have a Spektrum MR200 receiver which has worked faultlessly in a number of models. However as a result of multiple swaps between models the last inch or so of one of the two antenna leads has broken off. As I understand it, this last inch of un-screened wire is the antenna, the rest of the grey covered wire is effectively an extension lead.

      Can I cut back this broken wire to reveal a similar length of un-screened wire to act as a new antenna or do I have to replace the whole antenna wire (assuming its possible to get one) ? If I can cut the wire back to make a new antenna how critical is it that I get the right length?

      Any advice gratefully received.

          A quick google search shows it to be an easy fix. 2.4GHz antenna fix

          You'll want to do a range check after though.

          I would suggest measuring the length on another Spectrum Rx

            Steve,

            Thanks for a very quick and helpful response. I will give it a go and cut back the screen accordingly. I have measured another receiver antenna and it is 31.2 mm long as best I can tell. I think I will put a length of heat shrink over the whole length of both antennas as the step where the screen is cut back does create a weak spot which flexes and eventually cracks the conductor.  I will do a range test afterwards.
