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.

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. Another common place interference happens is from poorly shielded cables. Don t trap your antenna with any type of interference. Does metal roofing affect radio tv reception in the house.

Shielding helps to reduce electromagnetic interference. Thus buildings with a metal roof or many metal components will face difficulty watching tv. No one material will be the sole perpetrator. 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.

Generally if you do have poor cell phone service in your home it will be due to the cumulative effect of the materials used. Another culprit for poor reception is reflective surfaces. A metal roof discourages the transfer of signal by reflecting it away from you. A coaxial cable is used to transmit an over the air signal from the antenna to your television tuner.

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. 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. I sometimes use ham radio amateur radio as well. A metal roof is just one of many building materials that may weaken cell phone reception.

I use rabbit ear tv antenna to receive tv programs. 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. Image courtesy of wilson amplifiers. My fm radio also has an antenna.

Interference from cellular towers. The coaxial cable comes wrapped in shielding usually consisting of metal and plastic. Thankfully there are special indoor antennae which will circumvent this problem and help you watch tv despite having metal roofs. Does metal roof affect any of these.

With external antenna elevated a minimum of two feet from the metal roof you can be sure the reception will be captured and boosted. However it is possible some blockage or scattering of signals may occur. Common sources of over the air tv interference.
