INSTALLATION NOTES
For amateur base station installations it is recommended that
the forwards clearance in front of the antenna array is calculated
relative to the EIRP (Effective Isotropic Radiated Power). The
clearance height below the antenna array can be determined in
most cases from the RF power at the antenna input terminals.
As different exposure limits have been recommended for differ-
ent frequencies, a relative table shows a guideline for installa-
tion considerations.
Below 30 MHz, the recommended limits are specified in terms of
V/m or A/m fields as they are likely to fall within the near-field re-
gion. Similarly, the antennae may be physically short in terms of
electrical length and that the installation will require some an-
tenna matching device which can create local, high intensity
magnetic fields. Analysis of such MF installations is best consid-
ered in association with published guidance notes such as the
FCC OET Bulletin 65 Edition 97-01 and its annexes relative to
amateur transmitter installations. The EC recommended limits
are almost identical to the FCC specified 'uncontrolled' limits and
tables exist that show pre-calculated safe distances for different
antenna types for different frequency bands. Further information
can be found at http://www.arrl.org/.
• Typical amateur radio installation
Exposure distance assumes that the predominant radiation pat-
tern is forwards and that radiation vertically downwards is at
unity gain (sidelobe suppression is equal to main lobe gain). This
is true of almost every gain antenna today. Exposed persons are
assumed to be beneath the antenna array and have a typical
height to 1.8 m.
The figures assume the worst case emission of constant carrier.
For the bands 10 MHz and higher the following power density
limits have been recommended:
10 – 400 MHz 2 W/sq m
435 MHz 2.2 W/sq m

In all cases any possible risk depends on the transmitter being
activated for long periods. (actual recommendation limits are
specified as an average during 6 minutes) Normally the trans-
mitter is not active for long periods of time. Some radio licenses
will require that a timer circuit automatically cuts the transmitter
after 1–2 minutes etc.
Similarly some types of transmitter, SSB, CW, AM etc. have a
lower 'average' output power and the assessed risk is even
lower.
Versions of the IC-756PROII which display the "CE"
symbol on the serial number seal, comply with the
essential requirements of the European Radio and
Telecommunication Terminal Directive 1999/5/EC.
This warning symbol indicates that this equipment
operates in non-harmonised frequency bands
and/or may be subject to licensing conditions in the
country of use. Be sure to check that you have the
correct version of this radio or the correct program-
ming of this radio, to comply with national licensing
requirement.
