Other way around. The cap tunes the loop to resonance at the desired frequency while the gamma match transforms the impedance of the now tuned loop to 50 ohms. Resonance simply means there is no reactance at the feedpoint and the resulting impedance can be anything. It is the job of the gamma match to transform that impedance to 50 ohms. Good luck on finding a suitable air cap good for more than 5.5 Kv BTW. Most people use a vacuum variable for anything over 100 watts. How much power do you intend to run?
