Seems that any tiny streak of lightning will wipe out both rigs ! Do you
have any protection ?


My 43' vertical has an automatic tuner at the feed-point, 9 feet above
the ground. I physically disconnect the vertical wire. The horizontal
wires (radials) remain connected to the tuner and thus to the LMR400UF
that goes to my shack window in the house below. I have an AD-2 grounding
switch with gas plug at my elbow as I type. The shack is well grounded
with 3 8' rods plus "poultry netting" flat on the ground along the
fenceline. The path from my transceiver to Ground Proper is less than 2
meters. I have meticulously avoided letting "ground" anywhere near my
vertical dipoles. Other than the coax shield on the input to the tuner,
the 43' vertical is floating 9' in the air. You can get by on half a
dozen radials this way.

My GAP Titan DX vertical passes through a Diamond gas pill protector at
the feed-through. The loops have no protection at the moment. One goes to
my ICOM R75, the other to my Drake SW2. I will probably switch these over
to RG-6 75 Ohm after the baluns, and use cheesy CATV grounders.

We get a thunderstorm about once every 2 years here; interesting
microclimates in the canyons...
