EMF

Licence conditions require that due care is required with regard to public exposure to Electro-Magnetic Fields (EMF). The guidelines for this are ultimately set by ICNIRP.

For UK Amateurs, Schedule-3 of Ofcoms licence conditions require you to carefully assess anything that is on average >10W EIRP - a threshold that can easily be incurred by high gain microwave antennas. However don't panic - help is at hand...

Guidance

Work is in progress by the RSGB EMF Team, including an Ofcom-approved calculator and examples of Pre-Assessed Equipment Configurations (PAEC). Work on the latter is the basis of the following by UKuG and BATC volunteers:-
