Bob/ZL2CA in a recent message makes the same observations about grounded dipoles ie grounded loops in use in NZealand as I did in my experiments. Avoid such antennas if possible especially on 137 khz for transmitting. Even on receive they do not have the potential of a verticlal system. If you are stuck for space or other reasons and have to use any sort of loop on MF/LF then you must realize your limitations, and be content with limited communications distance. Often when a qso takes place between a station that is either qrp or has a poor antenna it is the other station with a better/larger antenna that is doing all the work, same on HF. 73 de Mal/G3KEV
