The use of a shunt inductor at the front-end is a good idea to prevent ESD demage.
But, Since its the spectral response, it's effective only in order to reduce low frequency, high voltage sparks coming from antenna.
It means that the inductor may protect front-end only if the source (the antenna) is high impedance at DC (i.e open dipole). The inductance is useless if the receiving antenna is a folded dipole (or every kind of loop).
Also, it's useless for high energy spikes, a gas discharge tube is much better!
Also it's useless for frequencies higher few GHz because practically a differential spark cannot enter trough the antenna, shunt back to back diodes are better.
