Interesting... the idea of awareness of, and ensuring safe EMF levels is within the expectations of an amateur radio license
, but not so much for many cruisers. This PDF (long!) seems to have a bit more background about the proposed changes: https://www.ofcom.org.uk/__data/asse...ion-update.pdf
It's probably worth keeping an eye out for an "Additional Guidance for Maritime Radio Users" which the above file mentions is still being drafted. My impression is there would be an expectation that you'd determine safe parameters for distance from the antenna
duration, so that you can make sure members of the "public" aren't over-exposed. Similarly if people have access to the antenna
, there'd be an expectation that you'd check and record
that the area is clear before transmitting.
Two examples come to mind. First, for antenna at the top of the mast
: between the distance and the maximum power, it's likely that few additional measures are needed. Second, for an antenna mounted on the pushpit next to an adjacent seat: A good portion of the cockpit
probably falls outside the safe exposure limits and a more proactive approach might be called for, either by recalling people from the area or significantly limiting transmission
time, and checking off a box in your radio log.
One last link; the EMF calculator they mention is an Excel spreadsheet, available from https://www.ofcom.org.uk/manage-your...emf/calculator
