[SADXA] My antenna meeting FCC limits?

[Carl Foster]

The limits are for 100% duty cycle like broadcasting. Even in a CW contest the duty cycle over an extended period is maybe 5%. For SSB, the duty cycle will be similar. This means you can multiply the calculated values by 0.05, which will be way below the exposure limit. 
These people are grasping at straws. I would not send them anything because they will misinterpret the data and use it against you.

I looked at the ARRL 

www.arrl.org/fcc-rf-exposure-regulations-the-station-evaluation
 and tried some calculations which ended up with mW/cm2 and uW/cm2 which has little meaning to the general public. I note the Table 4 in that article which gives distances for Maximum Permissible Exposure (MPE) and find that my antenna at 30 feet you need to be 9.9 feet from the antenna for 100 watts and 24 feet for 1000 watts, controlled, and 18 feet and 60 feet for uncontrolled distances. It is at 52 feet now and I could bring it down to 30 for visibility reasons. I estimate my neighbors back porch is at 150 feet and their house at 200 feet from the tower. Unfortunately, the neighbors, not being technical minded, except for medical issues, do not accept any reports I have sent to them.
