The antenna should be installed as high as possi-ble for maximum efficiency and that this installation heightshould be at least 5 meters above ground (or accessible)level. In the case where an antenna cannot be installed ata reasonable height, then the transmitter should neither becontinuously operated for long periods if any person is within5 meters of the antenna, nor operated at all if any person istouching the antenna.In all cases any possible risk depends on the transmitterbeing activated for long periods. (actual recommendationlimits are specified as an average of 6 minutes) Normally thetransmitter is not active for long periods of time. Some radiolicenses will require that a timer circuit automatically cuts thetransmitter after 1–2 minutes etc.Similarly some types of transmitter, SSB, CW, AM, etc. havea lower ‘average’ output power and the perceived risk is evenlower.
