DDS to amplifier plus antenna

[havoc88]

Hello there, I m new to LRLs.

I have some questions about the connection of DDS generators with an audio amplifier.
I saw that some people connect the signal generator to an audio amplifier and the amplifier's output stage to a loop antenna via a power transformer ?

Any info or idea how to output a signal to a wire antenna or loop antenna or any other way will be great.

Thanks.
