Hi,
...
Be advised that carbon build-up from furnace, boiler, or fireplace
operation
is extremely conductive and can soon form a static connection between an
antenna and the chimney-flue opening, and across various elements of the
antenna also. This is to be avoided. One poster's advice to keep the
antenna
mount "upwind" was well said. Avoiding a chimney mount (on a
working/operating flue) unless other options are not available is even
better.

I will not forget this advice !
Thanks

Thierry
