[Antennas] CB Intenna ?

[Hue Miller]

While working on my midlife cleanup, I recently rediscovered a CB curiosity 
I obtained long ago.
I bought this at some kind of store closeout.
It is "the Original CB Intenna". "Stop CB Rip Offs with the Intenna. It's 
Completely Inside - The
Car Skin Is The Antenna!"

Here's what it consists of: a small one inch metal cube box with 2 holes in 
it topside for screwdriver
adjustment of what's inside. One side has a coax female. The other side has 
a single insulated wire
about 20 inches long coming out.
Unfortunately I don't know where the instruction sheet is right now, but I 
think it's set up like this.
You mount the metal coupling box on your dashboard, plug the CB jumper coax 
into the coupler and the
other end to the CB. The single wire you run up to the rear view mirror and 
screw fasten it there so
that it actually makes contact with the car chassis. I think it must work by 
having the RF path from
the rear view mirror spot, around the two halves of the windshield, and back 
to the CB radio ground.

I wonder what your comments might be. I don't think I would want to use this 
with other than QRP,
that's for sure.  Maybe I will even try it out. What do you think is in the 
metal box? I'm almost
curious enuff to unsolder the bottom, but as the set package is whole, I 
prefer to keep it together
as an unusual collectible. Holding the thing up near strong light, I can see 
inside the adjustment
holes and see there, 2 small mica compression trimmers. So do you think this 
is just a capacitive
voltage divider (impedance divider), or do you think there's a small coil in 
there too, a pi network
( with low power components ).  Anyway, an odd item. I would think it would 
be pretty noisy
receive, while the engine was running. -Hue Miller K7HUE
