With most 2.4 antennas, you'll find the last inch is different to the rest of the antenna wire, this is the active portion, in actual fact this is the antenna, not the other part, the other part is just wire. As long as the active point stays the same, your ok. Why do I know this? Well i fly FPV aircraft and have modded 2.4 receivers to take an antenna that has a longer lead so I can locate the active portion away from any of my radio transmission equipment to minimise interference and maximise range
