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.

Read (google) about driving so called "magnetic loop antennas".

One of most important advantages of magnetic loop antennas is its relative low sensitivity to its position height over ground.
It should be resonant to TX working frequency. Q as high as possible. Orientation adaptable to needs on terrain.

In field of VLF frequencies and relative miniature antennas (in regard to wavelength), you can count to near field antenna propagation only.

The most simple driving of such type antennas is inductive (transformers like) driving.

A broad field of experiments. Happy hours with tests and good luck.
