Metal Roof Antenna Interference

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.

Metal roof antenna interference.

Another common place interference happens is from poorly shielded cables. 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. Interference from cellular towers. It would likely make a lousy antenna.

With external antenna elevated a minimum of two feet from the metal roof you can be sure the reception will be captured and boosted. My fm radio also has an antenna. However it is possible some blockage or scattering of signals may occur. Beware too of radiant barriers if you ve mounted your tv antenna in the attic.

Thankfully there are special indoor antennae which will circumvent this problem and help you watch tv despite having metal roofs. I use rabbit ear tv antenna to receive tv programs. Generally if you do have poor cell phone service in your home it will be due to the cumulative effect of the materials used. Thus buildings with a metal roof or many metal components will face difficulty watching tv.

Does metal roofing affect radio tv reception in the house. A metal roof discourages the transfer of signal by reflecting it away from you. A metal roof is just one of many building materials that may weaken cell phone reception. 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.

Common sources of over the air tv interference. So metal roofs don t actually interrupt cell phone reception. The coaxial cable comes wrapped in shielding usually consisting of metal and plastic. 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.

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. Shielding helps to reduce electromagnetic interference.
