Severe RF burn or death can result if antenna was touched
- Never mount this, or any other antenna near power lines or utility wires!!
- Any materials: ladders, ropes, or feedlines, that contact power lines
can conduct voltages that kill. Never trust insulation to protect you.
- Stay away from all power lines.
- Keep the antenna sitting stable on a flat surface, and make sure that it
will not fall and cause damage or injuries.
- Do not use The
Box Fan
loop outdoor in wet or rainy condition. Antenna

INDOOR USE
WARNING: Never operate this antenna where people are subject to high levels of
RF exposure, especially above 10 watts or above 14 MHz.
WARNING: Never use this antenna near RF sensitive medical devices such as
pacemakers.
Note :
If you are operating the antenna in the vertical polarization mode, make sure to place your
station in the null position of the antenna. Always face yourself to the opposite side of the antenna
(antenna behind your back). Human eyes are very sensitive to RF at high frequency, do not look at the
antenna directly when operating at high power.
This antenna can be used inside a wooden or non-metallic building.
Caution must be used when this
antenna is used indoor
, because the antenna generates strong electromagnetic fields. These fields can
induce considerable RF currents into wiring and other metallic items. A secondary concern is that the
effects of RF fields on humans is not yet fully understood.
