The Decca loading coil buildings had extensive >electrical heating as I recall. My loading coil lives outside in a shelter made of plastic sheet over a timber frame. To get rid of condensation, I have an old fan-heater in the bottom of the housing. The 2 heating elements are wired in series so it consumes roughly 500W instead of 2kW. This is so it runs much cooler than normal, just a warm draught, to avoid melting the plastic. Cheers, Jim Moritz 73 de M0BMU
