I think I'm finally starting to understand the reactance part of #impedance . You can increase the reactance by adding an inductor (X = jωL; ω = 2πf) and lower it by adding a capacitor (X = 1/(jωC)). You can use networks of variable capacitors and inductors if you want to adjust that (which affects SWR) while transmitting at the frequencies you want. :3c

And once you're done, you can replace those with fixed capacitors and inductors because you'll know what works! :D

Hmmm. I guess the structure of posts on here doesn't let us tag a reblog/boost with our own tags, since it is just the parent post being boosted. Closest would be a blank add on post...

Pour la première fois de ma vie quelqu'un réussit à me faire comprendre l'impédance.

What does "impedance matching" actually look like? (electricity waves)
