And yes, i think you are right when you guess that our short monoples have the same. The hope is, to get more. But who is able to tell us how to achieve? Experiments with 1.8 MHz are lowbandactivities concerning shortwaves but it is far away from 137 kHz. Well, we all know how hard it is to decrease the groundloss but is there anyone who will do the work for an EH-antenna? Most of you are asssuming a big construction by reasonable theoretical thinking but as far as i know nobody made the job. So may be the EH-antenna will be a never ending dream :-)) 73 Bernd, DF8ZR
