The title pretty much says it all. If there are any tech-heads out there that can offer advice on whether or not this will affect performance of the antenna, please chime in. It just so happens that the chimney is on the same side of the house that the antenna needs to point. The antenna is silver, like the chimney (Exterior double-wall stainless steel) and I felt it would blend nicely. As far as the cable (Triple shield RG-6) is concerned, I don't believe the exterior of the chimney gets hot enough to damage it. Any and all advice, comments or scathing retorts welcome! Thank you!
