INTRODUCTION & FEATURES
The MFJ-9232
Mini Loop Tuner
TM
resonates various lengths of wire to create a Hi-Q tuned-circuit
that functions as a transmitting loop. It uses special low-loss capacitors for high efficiency and
interfaces the Hi-Q transmitting loop circuit with any length of 50-Ohm coaxial cable.
No ground, radials, or counterpoise system are needed. The MFJ-9232
Mini Loop Tuner
TM
functions
with wire loops of any shape -- circle, square, rectangle etc. For highest efficiency, use wires
approaching one quarter wavelength erected in the shape of a circle.
The MFJ-9232
Mini Loop Tuner
TM
uses fixed wire lengths to cover roughly a 1.5:1 frequency ratio
(28-18 MHz, 10-7 MHz, etc.). Exact frequency coverage depends on each individual installation and
involves your choice of wire length, loop diameter, loop shape, height above ground level, plus other
stray factors in the immediate operating environment.

FEATURES:
•
Passive Network:
No power supply required.
•
Maximum Input Power
: 25 Watts, all modes
•
Small Physical Profile
:
1.5" D, 2.75" W, 4.0" H
•
Low Radiation Angle
: Radiation pattern rivals full size dipoles.
•
Quiet Reception
: Loops make extremely quiet receiving antennas. Hi-Q rejects overload from
out-of-band interference, rejects transmit harmonics.
•
Indoor Use
: Perfect for portable operation or antenna-restricted locations. Sets up quickly in
apartments and motel/hotel rooms.
