You don't need to actually attach the scope probe to the end of the coil.
Merely suspend it in the air a foot or so away.  We are talking about RF
frequencies here after all, and the probe will have no problem picking up
the signal.  Actually attaching it to the coil will load the coil (probe
capacitance etc.) thus  giving inaccurate results.
