Roof Insulation Blocks Antenna

The digital signals will not pass through metal surfaces.

Roof insulation blocks antenna.

Vents placed in the underside of the roof s overhang or soffit provide a means for air to get into the attic to help cool it in the summer months. It is noted that purlins are spaced nominally 5 on center. My question is about antenna placement. Describes the metal building roof base assembly as a roof with a thermal spacer block and the insulation is draped perpendicular over the purlins and compressed when the metal roof sheets are installed.

Non penetrating roof mount for satellite dishes wireless internet antennas etc uses standard concrete blocks to anchor to roof steel construction. How will spray foam insulation affect my tv signal if i decide to place a tv antenna in the attic. Attic antenna attic mount loss is at least 3 dbfor a 3 4 inch plywood roof covered with roofing paper and one layer of 3 tab asphalt shingles. A rock base 18 under the antenna site prevented me from burying a standard support post so this surface mount was the answer.

I don t know whether installing an rooftop antenna on a lower porch roof that does not have a radiant barrier might work. If you have foil backed or solar shield insulation in the roof joists then you will need to replace the insulation in the area surrounding the antenna or place the antenna outside. Unfortunately blow in insulation can drift into. It will hold 8 flat and two on edge.

I assume the ez hd tv antenna would work fine if placed it outside. If the home is partly built you could try an antenna with a small tv and see what happens. I recently had 6 inches of foam insulation installed in the attic roof decking and gables. What about inside the attic.

Try to keep as much distance as practical from these objects 6 feet or greater distance is ideal. Metal backed insulation in the attic or walls and metal exhaust vents and air ducts all block signals. Otherwise you may need to put the antenna on a pole far enough from the house to not be impacted by the radiant barrier.
