Not according to a dipmeter. For example, when a lo-pass
configuration Pi-network with a Q of 10 is tuned up, a dipmeter shows
that it is resonant about 7% lower in frequency.
If an L-network was resonant on the operating frequency, infinite
current would flow through it because the reactive components are
equal, opposite, in series, and not in parallel.
