Topband: protect my transmitter from atmospheric discharges

While I agree that an RFChoke to ground can help
drain static and a lightening surge protector is also a very good idea,
nothing outperforms the manual system of disconnecting the coax from the
radio at the entry point to the house or radio shack.  Further, a
grounding switch at the entry point further deflects Mother Nature's
electricity to ground.

While this may not be necessary in the
northern latitudes in winter, it is good practice from spring through
fall.

That also goes for antenna switch cables and rotator
control cables as well.

Nothing is totally fool proof but surge
protectors, static drains, disconnects and direct grounds all help protect
the radios and the structures as well.
