All:
Working on a ferrite antenna.

Ordered parts from Ocean state electronics, ( via website)

( http://www.oselectronics.com )

bought their 14-365 Pf variable capacitor and two ferrites:
one
FR4-33 #33 1/2" Diameter X 4" Long

and then

FERRITE "LOOP STIK" ANTENNA
band, 540KHz - 1600KHz. Measures 5/16" Dia. x 3 1/2" Long. Includes
mounting
bracket and wiring diagram. Q=25, L=788µH.
LA-540...................

- Now, follow this :

I figure I'll use the 8 inch loopstick for the ' Primary" antenna.
setting it
in a window..

Hook the " primary " up to the variable capacitor via about 10 feet of
co-ax
wire.
- so I can Tune it from 10 + feet away.

THEN use the "FERRITE "LOOP STIK" ANTENNA"( part LA-540.)
as a " transmitter"
setting it on top of my sangean 606A;

- So the primary can be tuned from far away,
still usable via the capacitor and 10 + feet of wire..

- Any thoughts on this ? Sheer folley? Intellectual Property Theft?
Genius ??

Happy as a Clam At High Tide..

One problem might come from the capacitance of the coax connected to the
tuning cap. It will restrict the tuning range. The extra capacitance
will have the same effect as not being able to open the cap all the way.
Otherwise, it should work. The tuning range problem will be lessened if
you connect the coax to a few turns of wire wrapped by the ground side
of the coil and use a similar coil on the other ferrite rod.
