I'm planning to use a 20-meter bandpass antenna for the 4 bands, connected to a 1:9 balun. However, I have an extra 4 meters of cable that I don't want to cut off. How should I handle this?

Currently, I'm considering two options: one is to fold it in reverse; the other is to let it naturally droop.
I would appreciate any advice or suggestions from experienced individuals. If there are better methods, please let me know.
