>>  For SWL you can also use your metal rain gutters, metal window frames,
>>  metal storage shed, the metal siding on the house, any large or long
>>  piece of metal. Wrap a wire around the house (that's my antenna).
>>  Zig-Zag a wire back and forth across the attic, have fun.
>   What about corrugated iron roofs? Any experience?
No, but for SWL you can use just about anything made of metal that's larger
than 2 feet or so. The bigger the better. Try it. Who knows?
