Those high-frequency, high-voltage outputs might have very limited amperage (often delivering skin-effect limited currents at high frequencies), but they can still pack quite a snap, cause nasty RF burns, or ionize the air right through a fluorescent tube or neon bulb without direct contact. https://www.peach-pass.com

You can’t wind a coil without lots of capacitance between the turns, between the ends etc.
Small rubber antennas for VHF have quite a small a diametre and few turns. A 20 cm coil with diametre 25 mm wound with 0,5 mm will have a resonance frequency of a few MHz, less if the battery etc acts as a ballast.

https://www.youtube.com/watch?v=HHsG_dBZyCM

A simplified version of the Slayer Exciter solid state Tesla coil using only a 10F supercapacitor, a 2N3904 npn transistor and an 85 turn coil.
It requires an electromagnetic pulse to start resonating at very high frequency.
The larger model uses a 2N2222 transistor.
