IMPORTANT: EMF for Microwaves and QO100 - A joint BATC/UK Microwave Group presentation 16th October 2021

John Quarmby

As I expect you are aware, UK stations must have Electromagnetic Field (EMF) assessments in place for operation above 110MHz from 18th November 2021. Some RSGB guidance on EMF is here:

The RSGB has been developing a tool that incorporates the Ofcom EMF Calculator but extends the models to include single and multiple Yagis plus various sizes of dish antennas, and takes account of the directivity of the antenna.

Ian GM3SEK, a key member of the team that developed the spreadsheet tool, will be talking about its application to Microwaves and QO100 operation on 16th October at 13:30pm, in a joint BATC/UK Microwave Group presentation during the BATC Convention.

Registration is not required, just go to to view the talk. Full details of the BATC CAT21 program are available here <>

This is an important topic for all that operate on VHF and above, and Ian will dispense invaluable practical advice on how to assess your dishes and yagis in the microwave bands. Not to be missed!
