Dr Jonathan Chisum’s YouTube webinar on Tech 101 provides insights into the often misunderstood world of antennas, and the key to making them work properly.
Simply put, an antenna’s performance is all about size, specifically tuning its dimensions to the target frequency, whether it be for a drone, wifi, defence work, or RF hacking.
He explains the real-world application of antenna theory, going further than textbooks, and makes it accessible in bitesized chunks for hackers and those in the electronics industry who want to improve their signal.
Homebrew and DIY hacks are encouraged, as antenna size and cost are not always a barrier to experimenting, and signal improvement can be made with small adjustments.
The focus is on wavelength and how tuning antenna dimensions to a target frequency makes the difference between a good and a bad signal.
