I think it would increase the coil losses, compared to a higher inductance coil of same Q, without the capacitor. Pcoil = I*U/Q At same radiated power, you'll have the same voltage but higher coil c
H indeed, parallel capacitor will increase the coil current, but on the other hand you will get resonance with a smaller inductance. I haven't done any calculation on the case (yet), but probably bo
... but you could additionally increase wire diameter by sqrt(2) for the same coil length. Assuming skin effect regime, this will decrease R by another factor of sqrt(2). In other words, same coil Q
