I am trying to figure out what procedure they are using to measure the rf amps and where all the rf is going because the signals heard on LF are low to average around the UK and in EU. I am running a few hundred watts also and get nothing like the rf amperage that others are claiming. My system is designed for 50 ohms throughout and matched accordingly at the base of the antenna via a coil with max of 400 microH. Others must have exceptional antenna and ground efficiency. Maybe most are heating up the ground around the antenna, and the loading coil ,whereas my couple of amps are being radiated by the antenna. Maybe someone knows the answer. G3KEV
