INST ALLA TION NOTES For amateur base station installations it is recom- mended that the clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the an- tenna array can be determined in most cases from the RF power at the antenna input terminals. Different exposure [...]
