Back to back: Take your two diodes and install them in parallel, but
with one 'pointing' in the opposite direction. The idea is that, because
each diode will conduct when the voltage rises above it's threashold, it
doesn't matter if the spike is positive or negative. A radio signal is
highly unlikely to be powerful enough to force either diode to conduct
(and if it did, they'll protect the RX front end).

I don't think they'd help much however! You only have to think about the
kind of potential in a static build-up to decide that you do not want to
rely on a pair of diodes to keep everything calm. Far better to make
sure your aerial has a DIRECT path to earth - a low impedence one at
that. Best way to avoid static damage? Disconnect the hardware from the
wire when you think there's static about. Oh - and avoid using
headphones....


Good luck.

OK I get it now.

As for an earth ground......I found a nice fat copper braided wire
coming off the metal roof lightning protectors (this is an old
farmhouse) down the side of the house going deep into the ground.

I suspect if I solder a nice fat 12 guage wire to my random wire where
it meets my coax it would suffice in this regard. Additionaly I will
run another wire to this ground from my tuner.

thanks,
