How would I couple the output of an amplifier from an oscillator to an antenna?

I am using a 1 MHz crystal in a colpitts oscillator circuit. I have no idea how to couple the output into an antenna though.

Why do you want to do that? It's likely illegal.

Definitely illegal, and you could easily find this information on Google if you wanted to.

I was planning on using an antenna that would only broadcast it about 5-20 feet or so. And I have searched Google for an hour, mulling the exact search phrase over and over, and I cannot find anything at all that answers the question exactly. That's why I came to forum.

I'd use solder

Ok, capacitively couple it. 1nF should do it from the emitter or collector, source or drain which isn't common.
Inductively coupling, 4 or 5 turns around the ferrite, one side to earth, the other to the wire.
