[. . . ] Conditions ·In combination with PS-125 116 19 ABOUT CE 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 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. [. . . ]
