By now you know that the building materials are a big factor.
I believe we had it set up with a 4 way splitter.
The only concern with attic mounted antennas is the space available to you for mounting.
Also i don t know if bad weather will affect the signal.

Unfortunately this can also block your tv reception forcing your hand in setting up the antenna on the roof.

Roofing materials like shingles concrete and especially metal roofing can significantly weaken or sometimes completely block the signal from passing through.
The material can be metal or pvc.
It s a long way from the rabbit ear designs you might think of when picturing indoor antennas and much cooler looking than the metal contraptions often found outdoors.

Provided you have a large attic or don t mind putting it on the roof we don t see any reason not to give this model a shot.

Here is our tvfool to give you a comparison.
Is it of the magnitude of reaching only half the distance or is the loss less significant.
