A Marconi antenna on 472kHz

So that I can better quantify the performance of my various earth electrode "antennas" I have today erected a 9m long top loaded Marconi vertical for 472kHz. Initial antenna current measurements suggest the ERP is up around 10dB to around 100mW. My plan is to run this overnight again and then tomorrow compare the signal reports against those with my smaller compromise Marconi and my two earth electrode antenna configurations.
