I bought this many years ago, it is on a wood base, with a pre-amp and coil
which could be removed to change freq coverage. 3 coils included. . Uses 9v
battery, RCA jack for output. Ferrites are multiple and long (22"). Comes with
3 coils . Has plastic azimuth on base to show direction, and of course tilts to
null out certain skywaves. It did not work when I got it; I've lost
instructions, and am selling as is. This was a semi-commercial product, not to
standard of Palomar or Kiwa, but obviously made in small lots. Since it came
from AM-DXer, one of the coils is proably AM. Will pack carefully. $85 plus
shipping. Paypal.
