My fm radio also has an antenna.
Metal roof antenna interference.
Shielding helps to reduce electromagnetic interference.
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.
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.
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.
However it is possible some blockage or scattering of signals may occur.
I sometimes use ham radio amateur radio as well.
So metal roofs don t actually interrupt cell phone reception.
Does metal roofing affect radio tv reception in the house.
Beware too of radiant barriers if you ve mounted your tv antenna in the attic.
I use rabbit ear tv antenna to receive tv programs.
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.

A metal roof is just one of many building materials that may weaken cell phone reception.
It would likely make a lousy antenna.
Thus buildings with a metal roof or many metal components will face difficulty watching tv.
Another culprit for poor reception is reflective surfaces.
The coaxial cable comes wrapped in shielding usually consisting of metal and plastic.
Don t trap your antenna with any type of interference.
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.
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.
Common sources of over the air tv interference.
Does metal roof affect any of these.
Thankfully there are special indoor antennae which will circumvent this problem and help you watch tv despite having metal roofs.
Generally if you do have poor cell phone service in your home it will be due to the cumulative effect of the materials used.
A coaxial cable is used to transmit an over the air signal from the antenna to your television tuner.
With external antenna elevated a minimum of two feet from the metal roof you can be sure the reception will be captured and boosted.
Interference from cellular towers.
