INSTALLATION NOTES

For amateur base station installations it is recom- mended that the forwards clearance in front of the an- tenna 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 different frequencies, a relative table shows a guideline for installation 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 region. Similarly, the antennae may be physically short in terms of electrical length and that the installation will require some antenna matching device which can create local, high intensity magnetic fields. Analysis of such MF installations is best considered in association with published guidance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter instal- lations. The EC recommended limits are almost identi- cal to the FCC specified ‘uncontrolled’ limits and tables exist that show pre-calculated safe distances for differ- ent antenna types for different frequency bands. Fur- ther information can be found at http://www.arrl.org/.

• Typical amateur radio installation

Exposure distance assumes that the predominant ra- diation pattern 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.

In all cases any possible risk depends on the transmit- ter being activated for long periods. (actual recom- mendation limits are specified as an average during 6 minutes) Normally the transmitter 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-706MKIIG which display the “CE” symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Direc- tive 1999/5/EC.

This warning symbol indicates that this equip- ment operates in non-harmonised frequency bands and/or may be subject to licensing con- ditions in the country of use. Be sure to check that you have the correct version of this radio or the correct programming of this radio, to com- ply with national licensing requirement.

The figures assume the worst case emission of con- stant carrier.
