Hi, I'm Snage. I'll be showing you around RF, Wireless and Telecommunications.

Today's lesson, "Wavelength Sets the Rules", shows how frequency shapes every radio.

Why is an AM mast about 75 m tall while a 5G phone antenna is a few millimeters wide?

How does a microwave oven door full of holes stop the microwaves but not the light?

And why is 60 GHz a good pick inside a room and a poor one for long hops?
