Antenna Signal Loss In Attic

Your rights regarding antenna installations on your property are explained in more detail on the fcc s web site.

Antenna signal loss in attic.

However you need to make sure that you are getting some signal passing through into the attic. The coaxial cable comes wrapped in shielding usually consisting of metal and plastic. Random signal reflections and absorptions may also drastically degrade the performance of an attic antenna. While that s not a huge amount it can be significant when combined with other signal loss factors insulation and metallic surfaces.

Bare copper antenna wire stapled directly on wood rafters causes loss of rf signal energy. A coaxial cable is used to transmit an over the air signal from the antenna to your television tuner. How do i aim an antenna for digital television. Metal backed insulation in the attic or walls and metal exhaust vents and air ducts all block signals.

The attic shortwave antenna wire this is the most importantaspect to improve. Mounting outside antenna in the attic ironically helps in such a situation and allows the signal to be weakened by the roofing materials. For example a brick wall can cause a signal loss of up to 8 decibels. Shielding helps to reduce electromagnetic interference.

If the cable is poorly shielded you can get signal loss and interference. Rescan your channel monthly. In general you can lose up to 40 50 of your signal s strength from an attic installation due to the loss from roofing materials but with proper installation and the right antenna you can overcome some of this loss and be successful. 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.

This actually would help the signal booster to work at maximum performance. Some buildings may have particularly thick walls which can significantly decrease an antenna s functionality. Install a signal amplifier or booster between the antenna and receiver to increase the signal strength. With time bare copper oxidizes the wood where the wire is tightly stapled to absorbs some of this oxidization and forms a loose yet lossy bond with the wire.

This antenna features a patented design that generates enough power to provide a signal to multiple televisions in one home even when located in an attic and it can support a variety of broadcast types including hdtv 1080p and even 4k ultra hd. Please wait a few minutes to see if the reception is getting better before the move.
