RWB,

Making the "Protected" Antenna-to-Radio Connection
http://groups.yahoo.com/group/Shortw.../message/14289

At least for 'portable' AM/FM Shortwave Radios that have an
External Antenna Connection and using an Out-Side Antenna;
the Antenna-to-Radio "GIZMOE" 'Connector' Box seems to work
OK and incorporate many of the items that you mentioned.

Hi Joe and All:

I was taught the NE2 thing by an old ham when I first
got into servicing. But then the solid state stuff began
showing up with fried RF transistors. It was apparent
that the neons didn't fire until it was too late - good
for hollow state, but not transistors. So I always put
a 1/4meg or 1/2 meg resistor across the input for a
static bleeder. But in the case of a nearby strike,
apparently the emf would surge past the resistor, So back
went the NE2 along with the resistor. Maybe it's me, but
I don't trust Transorbs or Surgistors. I now put in a
lower value resistor, like a 5 or 10K, in series with
a coil, tuned to the lowest receiving frequency, and
across that an NE2. Maybe it's dumb luck, or maybe it's
good practice, but I haven't had any of those radios
fail since ... mine included - knock on wood (sound of
me rapping my knuckles on my head).

I once had a little mini-box on the shelf, which fed my
long wire to the shack's switch box. It had 3 switches:
antenna shunt, resistor in/out, NE2 in/out. If I was
brave enough to disconnect the switch box, and leave the
mini-box inline, I could watch the bulb flash - bright
and often - under certain weather conditions. More than
once I got zapped by handling that antenna connector
during a dry snowfall. It's more fun to watch the flashing
than to conduct the static with your body. Better yet,
it's better to keep the bleeder resistor inline and not
play with the little blue sparks.

Now, the outdoor balun does all the bleeding
- much better arrangement.

Okay, jes thought I'd share that.

Bob
