Hi Wayne
you also need to consider power levels in your planning. the vk3um EMR calc software is very handy for visualising the situation. I used this as a planning aid for a VHF high power permit application some years ago and learnt quite a bit from it during the process. I say this about power because an antenna is only a threat once it is enegised and the level of threat is dependant on the power level being used. I know most of the 1KW HP trial permit holders failed on EMR because parts of antennas were to 'exposed' to human contact. What that actually was I am unsure but using the VK3UM software you can see what exclusion zone it gives you for an antenna / power level combination and not rely on us bush laywers in forums :-)
