General Caution Notes
The Model ATH200M1G-1 Antenna is capable of producing output voltages which are dangerous to human life
as well as causing serious RF burns.
NEVER walk in front of the horn when it is radiating.
Operation of this antenna and associated equipment should only be performed by personnel thoroughly familiar
with the hazards inherent to this type of equipment.
The American National Standards Institute (ANSI) has created a new standard (C95.1-1982) which recommends
safety levels to prevent harmful exposure to radio frequency electro-magnetic fields. Over the operating
frequency range of the antenna, (200-1000MHz) maximum whole body exposure averaged over 0.1 hours can be
calculated as follows:
Power Density (mW/cm
2
)
= frequency
300
Therefore, at 1000 MHz
1000 = 3.34 mW/cm
2
300
300 (safe operating level)
When operating the ATH200M1G-1 Antenna at 1000MHz at 1000 watts input, the power density is 520 mW/cm.
This is approximately 155 times more than the 3.34 mW/cm specified in ANSI 95.1-1982 as a safe level with
respect to human exposure to RF fields.
CAUTION:
High concentrated RF fields can be transmitted by this antenna. Take
proper precautions when attempting any measurement. Above all, do not
walk in front of antenna when it is radiating.
