As they bury their heads in the sand, the rays are exposed to predators. A fine-tuned antenna sticking out of their backsides would help the rays detect trouble before it was too late.

Transmission line transformers are similar to regular transformers, except that the former relies on transmission line action to transfer energy rather than magnetic flux and provides no DC isolation.

Define your operating goals to narrow your options. Beginners may prioritize simple, plug-and-play tools for reliability, like an easy-to-tune antenna or a basic power source. If you often operate in ...
