I have re-engineered the far end and have improved things. It seems that the far end insulation was not as good as it could be (1m of plastic pipe). I have now restored the current to what it was before the change by adding an extra insulator in each leg. This shows that it is just as important to keep the far end =extremely= well insulated as it is to minimise losses at the high current end. The antenna still needs a little work to make it as mechanically stable as possible, but it performs well. I have just had to put a small attenuator in the front end of the receiver! I look forward to some reports at the weekend. Mike, G3XDV (IO91VT) http://www.dennison.demon.co.uk/activity.htm
