Back on the air now and I have lined the ATU hut with metal, both aluminium sheet and aluminium cooking foil! All this is bonded to earth. Everything is much more docile with less corona from the top of the coil so I thought maybe current was down. I measured it and current (measured on the antenna feeder outside the box) is 10 per-cent better for the same input power. I therefore recommend putting your loading coils in large earthed metal boxes! It avoids losing power in nearby lossy structures and may contain a melt-down better..... I should be joing in the fun again tonight. 73. Dave G3YXM.
