From the field
The same lessons come up again and again from people actually doing the job:
People think RF engineering is just fixing antennas. It's deep engineering — I design and optimise the wireless systems that carry every signal through the air, mastering the physics of radio waves. It's invisible work, but without it there's no mobile, no Wi-Fi, no satellite.

The expertise is genuinely scarce, which makes it well-paid and in demand. RF is hard — it takes a real grounding in physics and engineering, and not many people specialise in it. That scarcity, plus the endless growth of wireless, keeps RF engineers very employable.
