You should start your own thread for this and provide a link to your TV Fool report. But your situation is very easy. Assuming you want just the stations at 324/327 degrees which are close and extremely strong a small VHF/UHF antenna should work in the attic. I'd go with the Winegard HD7694P if it'll fit or maybe the smaller RCA ANT751. Do not use a preamp. The stations are too strong and there will be overload.

If you want all those "LD" stations then that's another story.

I have attached a "TV Fool" analysis below

Thanks in advance.
Post a live link, not a photo. Do you care about the stations in red and yellow?

The stations in green should be all I need.

Is the range of the recommended antennas required because of signal loss associated with an attic installation?

Antennas don't have ranges and are not rated in miles so I'm not sure what you're asking. There is signal loss in an attic and reflections inside the attic can cause problems regardless of the signal strength. You should be able to receive all the stations in green with the antenna pointed at about 305 degrees.

In that case you shouldn't have much trouble barring unforseen attic reflections. I agree with Calaveras.

How many televisions? How much cable between the antenna and your distribution? Between the distribution and the televisions?

Two television.
Approximately 20 feet to the distribution point
Approximately 30 feet for 1 of the sets from the distribution point and 50 feet for the second.

"Attic Loss" varies a LOT due to construction details and Roofing Materials (Metal is the WORST and Red Spanish Tile is also fairly high with wood shingles LOW....until it gets WET)....and whether signals are blocked by Aluminized Mylar "Thermal Wrap", Foil Backed Insulation or Chicken Wire in Stucco (popular in my location)....and BTW, shooting through END of the Attic may be LOWER Loss...esp. if remove Metal Mylar/Foil. OTOH, Windows can let signal leak in, where they are reflected around inside....unless they have a LowE Thermal [Metal] coating...which has about 20 dB Loss. Based on looking at MANY different OTA Tests over MANY years, on the average there is about 13 dB +/- 7 dB difference between Roof and Attic Mounted Antenna....which is a HUGE difference.

One other possibility should the cool, wife-pleasing invisible attic installation prove problematic due to the various interfering materials mentioned: a rather small, unobtrusive directional combination VHF/UHF antenna would not even be visible from the ground depending on mounting location. The ELEV-J3 would be one possibility. Mounted low at the peak of the roof it would be hard to see.

Inside the attic, the largest, highest-gain Yagi you can fit has the best chancing of working with the diminshed signal and multipath. If you have any metal in the roof, or foil insulation applied to the roof sheeting, you may want to consider a small, discreet outdoor antenna instead.
