OPERATION
The most important aspect of using the MFJ-9232
Mini Loop Tuner
TM
is it opens-up opportunity for
Hams to once again
experiment
while enjoying operating at the same time. Imagine how exciting it
can be to establish contact with a distant station using an antenna that you designed for the first time.
Even more so, what if you are just using a few watts, and the antenna is just a few feet away from
your operating position
inside your home
!
Operation is simple, but must follow specific steps in a specific order. Moreover, you must have first
consulted the RF Hazards section of this manual to ensure compliance with established standards for
Minimum Permissible Exposure (MPE) to certain levels of RF radiation.
WARNING
DO NOT touch or come into contact with Loop Connectors or Loop
Antenna while transmitting
YOU CAN BE SERIOUSLY INJURED !!!
Step 1
Place the MFJ-9232
Mini Loop Tuner
TM
at the chosen place of operation, and connect the loop
antenna to the wing nut terminals on the rear panel.
Step 2
Using a pre-cut prepared wire and fasteners (non-conductive plastic clothespins for example) form a
loop to enclose as much area as possible (for example, clothespin a wire loop to a curtain around a
window frame). A circle encloses the maximum area. Otherwise, drape it across bookcases or similar
objects to fashion a loop of sorts to use. If the loop antenna is rigid, then place the
Mini Loop Tuner
TM
in a position to accommodate its particular shape and size.
Step 3
Complete the typical MFJ-9232
Mini Loop Tuner
TM
setup configuration as illustrated in Figure 3 of
this manual.
Step 4
Make the following preliminary settings on the controls of the Mini Loop Tuner:
•
TUNING control to position “Low Freq”.
•
MATCHING control to position “Min C”.
