Neil E. HodgesI 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

What is Static VAR Compensator (SVC)? Working Principle, Diagram & Advantages - Electrical and Electronics Blog
A Static VAR Compensator (SVC) is a shunt connected static VAR generator or absorber in which control of certain power system parameters are achieved by exchanging
