[Premium-Rx] Lightning hitting your Premium RX

My coax is under ground and I throw a pipe over the open wire line that
pulls it to the ground
when there is a storm coming or I'm out of town. I should also remove it
from the house.
Also good to coil up the coax to make a RF choke before it enters the
building.
Pray and pray hard also helps.

_Everywhere_, most likely, but starting at the least-expected point.
I'm at work, and the rig is at home right now -- with both antenna feeds
disconnected from the tuner _and_ with power disconnected from TX and RX.
The only remaining connection is to ground, and that does still present a
potential[1] vulnerability.
Any time T-storms are predicted in the area, the antenna feeds get pulled
loose, as does power, before I go to work. While it's a real pain to avoid
cross-threading the @#$%^&*( PL-259 sleeves when I put stuff back together,
it beats forking over bunches of bux for a new transmitter and/or receiver.
[1] No pun intended, I assure you.
