Thanks to StephanieS and GroundUrMast for their suggestions. My first NY's resolution is to finish my antenna project.
I did purchase an ANT-751 and am convinced it needs to mount on the roof, not inside. My 2 choices seem to be either on the chimney, or directly to the roof. I prefer to not put any additional holes into the roof. What are the pros and cons of installing on a chimney?
I'm also convinced I don't need to worry about transmitters to the north, or the ones on Gold Mountain (headings 249°/250°). I would like to pick up the transmissions from Tiger Mountain (heading 130°) but will try to do so with my single antenna...and then follow up on Ground's advice if a 2nd antenna is warranted.
I've attached a view of my roof showing the chimney, as well as views from the chimney facing headings 196° and 130°. I'm interested in any observations or suggestions from the community. Thanks again, and Happy New Year!
