CTS 223: How Does an Antenna Work?

What this episode covers

In this episode, we have Ben Robson, RF Engineer, with us to explain how an antenna works. He went into great details on how the antenna works. It is probably the longest episode we have recorded so far! But it is well worth it! Thank you Ben for coming on the show to educate us! Enjoy.
