New FCC Rules require all amateurs to do an evaluation of their station for potential harm due to RF exposure. There is now no need to learn complicated antenna modelling programs. It's actually EASIER than the exposure tables you saw on your exam in years past. The entire process takes about 5 minutes, to print a page for each frequency you transmit on. I use standard dipoles hanging from trees, and I have an ALS-1300 amp, as well as a 2 meter rig and an AEA Isopole antenna. It all passed fine. Do yours today and keep it in a file, in case of any questions later.
