My report: http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3db97dccc4dae8bd

We're only interested in the top 5 stations that are (fortunately) all on the 70° heading.

We'd really, really, REALLY prefer to mount the antenna in the attic if at all possible. Fortunately, the direction it'll be facing doesn't shoot through the roof, just the plywood sheathing & vinyl siding, but there are trees in that direction (Roof mounting would still have the trees). The antenna will be connected through ~100ft of RG6 to a single Tivo, so while the coax length isn't ideal, at least there aren't any splitters inline.

An antenna suggestion would be appreciated. The logistics of the mount in the attic mean that an antenna that has elements only on one side of the mast would be far easier to hang, than an antenna that has elements on both the front and back of the mast. However, that's not mandatory, just something I desire as the poor schmuck who has to install it.

Thanks in advance.

P.S. For reference, my neighbor (whose house is not far away, but close to 100' lower in elevation) has a very basic "BBQ grill rack" looking antenna (probably something like a Channel Master cm-4220) on his roof with an old Blonder Tongue pre-amp, and gets *everything*, no issues. Just for shits & grins, I did a report on his house. It's amazing he pulls the VHF-High channels in so well. http://www.tvfool.com/?option=com_wrapper&Itemid=29&q=id%3db97d44ffb85bb4

Also, here's a google earth view of where the antenna will be pointed. I'm assuming that the TVfool report accounts for the trees?

Read the bottom of the page under your plot.

"Please understand that this is a simulation and can only be treated as a rough approximation. Reception at your location is affected by many factors such as multipath, antenna gain, receiver sensitivity, buildings, and trees - which are not taken into account. Your mileage may vary."

Signal loss in the attic is difficult to predict. Try a temporary setup at different locations in the attic before drilling any holes. If it doesn't work, add a preamp. If it still doesn't work, you will have to go outside. Try the Winegard HD7694P antenna.

You have some strong local FM signals that might cause interference to TV reception; an FM filter might be needed.
