Common sources of over the air tv interference.
Metal roof antenna interference.
On using a metal roof as an antenna the joints between panels are likely not soldered and are likely to form corroded diode junctions that generate rfi.
Does metal roof affect any of these.
Thus buildings with a metal roof or many metal components will face difficulty watching tv.
A metal roof discourages the transfer of signal by reflecting it away from you.
If you have aluminum siding or a metal roof be sure to mount the sky outside away from the siding or above the metal roof if possible.
Don t trap your antenna with any type of interference.
Generally if you do have poor cell phone service in your home it will be due to the cumulative effect of the materials used.
In a nutshell metal roof or not the type of building material is irrelevant the cell phone signal will be injected into the internal space via a special high quality cable.
Thankfully there are special indoor antennae which will circumvent this problem and help you watch tv despite having metal roofs.
Those planning to install an antenna in their attic should also choose a different location if they have a radiant heat barrier or metal roof.
Over the air antennas should never be placed in basements or in windows with metallic film security bars or mesh as this will obstruct signals.
It would likely make a lousy antenna.
The coaxial cable comes wrapped in shielding usually consisting of metal and plastic.
With external antenna elevated a minimum of two feet from the metal roof you can be sure the reception will be captured and boosted.
No one material will be the sole perpetrator.
If you have a metal roof for instance make sure the outdoor antenna is mounted at least one meter about 3 3 feet above it to reduce any effects of interference.

Another culprit for poor reception is reflective surfaces.
Shielding helps to reduce electromagnetic interference.
My fm radio also has an antenna.
Does metal roofing affect radio tv reception in the house.
A metal roof is just one of many building materials that may weaken cell phone reception.
So metal roofs don t actually interrupt cell phone reception.
Interference from cellular towers.
I use rabbit ear tv antenna to receive tv programs.
However it is possible some blockage or scattering of signals may occur.
I sometimes use ham radio amateur radio as well.
