Topband: Detuning an Antenna

Good Morning Gents:

Please let me pose the following question:

I have an inverted L. At the bottom is a matching network consisting 
of  two variable capacitors & an inductor in a T Network. Of course, 
the capacitors are in series with each other, the coax, and antenna, 
with the inductor connected between the junction of the capacitors & 
ground.  If I insert another inductor in series with the present one 
during RX, will that detune the antenna or just present a different 
load to the antenna leaving it resonant and free to reradiate?

Thanks & 73,
Mike, W5UC
