Not much force is required to unscrew the assembly.

I will be doing the mods but using G30 insulated wire (also available at Radio Shack) in the SL antenna and see if I can cram 75 cm in that small space.

I know that 75cm of G26 insulated wire will fit inside the R170 antenna (with some room to spare), but haven't had the chance to solder it in place or test it out. I will report back after completing both mods this weekend.
