How to protect a RF chip from thunderstorm static electricity?
One method uses a choke to ground that is "high" impedance at 800 MHz or whatever RF is and low impedance at 0 to 30MHz.   High , that is relative to antenna impedance.

The other method is to confirm no ground shift  for lightning discharge to ground . i.e. a deep ground rod to avoid shield pickup.

The 3rd method is to use a direction loop antenna which is inherently low impedance below 30MHz, say.

The 4th is a half wave loop and a whip antenna in some combination, maybe horizontal loop and vertical whip with impedance transformed cable length for matched Z and omni-direction in horizontal plane.

To reduce the risk of direct hits requires an array of sharp tipped rods 10m above your antenna and deeper than your ground rod. There will still be inductive coupling so double shield or semi-rigid coax performs better. The same is used on power substations. But expensive and a double edge "saber" on a mountain top.  It would also attract higher probability of nearer strikes.
