Get the best performance out of your attic mounted HDTV antenna.
Before you install Determine the following:
- Are some TV signals too weak to be received with an attic mounted TV antenna?
- What building materials will the TV signal have to penetrate to reach the antenna?
- Is there enough space in the attic for a suitably sized TV antenna?
- How much signal will be lost when compared to mounting the antenna outside?
- How to select the best TV antenna for my attic.
Building materials play a role in determining the success of an attic mounted TV antenna. A while back I connected a TV antenna to my field strength meter. A field strength meter measures the signal strength of any individual TV signal. I grabbed a piece of 7/8" OSB particle board and tested the signal strength of several TV channels without the board in front of the TV antenna. Then I placed the board at a distance of about 6 feet in front of the antenna. I found that on every channel the signal strength decreased from as little as 10% to as much 30% with the board in front of the antenna. The closer I moved the board to the antenna the weaker the signal became, as I moved it further away the signals became stronger. Keep this in mind when placing the antenna in the attic. The further you can keep the antenna from any signal obstruction in front of the antenna the better.
Do you have a metal, brick, masonry or tile roof? If the station transmitter direction requires the signal to penetrate any of these materials your chances of success are diminished. However, if the TV transmitter direction allows the signal to penetrate through wood, common roofing or vinyl siding to reach the antenna you should be okay. A plywood roof covered by a single layer of asphalt shingles is best. Many homes have a 2-3 foot wide metal stripping that can't be seen installed under the roof shingles at the bottom edge of the roof. Always install the antenna above this point so the transmitter signal line of sight to the antenna is above or below the metal stripping.
Do the attic sidewalls have metal siding, foil faced insulation, brick, or masonry of any kind? All of these materials are nasty signal blockers. It;s best to try to place the antenna in a position so the line of sight from the TV transmitters to the antenna is not block by any of the above mentioned materials.
Signal loss attic installation VS. outside. By now you know that the building materials are a big factor. TV antenna elevation will also play a role in signal strength. The extra antenna elevation that can be gained by mounting the antenna outside above the roof line must be considered. Weaker TV signals and TV signals from a greater distance will be effected most by antenna elevation. Will the extra outside elevation place the antenna above surrounding signal obstructions such as neighbors homes, hills etc.christmas quiz questions charity christmas cards christmas bank holidays 2022 real christmas tree bath christmas market christmas decorations 2022 christmas party outfit small christmas tree garland christmas park christmas christmas cookies christmas events near me christmas trees near me the christmas chronicles christmas mugs christmas ideas crisis at christmas london christmas market christmas party dresses christmas number 1 christmas tree drawing driving home for christmas john lewis christmas advert christmas lights outdoor christmas chronicles 2 sally nightmare before christmas prelit christmas trees christmas gif personalised christmas baubles christmas gifts for men christmas presents for mum christmas carol christmas markets 2022 uk wilko christmas tree christmas cake decorations lidl christmas jumper christmas carol vorderman christmas card christmas aesthetic leeds christmas market 2022 christmas desserts christmas acrylic nails christmas cupcakes state pension christmas bonus christmas candles lloyd christmas christmas onesie exeter christmas market rockin around the christmas tree covid lockdown christmas christmas biscuits christmas scene m and s christmas food boys christmas jumper kids christmas jumpers rochester christmas market when is christmas mini christmas tree do they know it's christmas christmas socks matching family christmas pajamas christmas table runner christmas border christmas jumper mens black christmas christmas garland with lights all i want for christmas is you lyrics christmas gonk thursford christmas spectacular christmas cards 2022 christmas family pyjamas dog christmas jumper christmas jumpers uk christmas eve box ideas mumsnet christmas asda christmas pyjamas christmas sale christmas eve box fillers covid lockdown after christmas wham last christmas nottingham christmas market 2022 outdoor christmas tree christmas holidays 2022 christmas window decorations christmas t shirts girls christmas jumper christmas decorations sale how many days to christmas christmas hampers uk christmas flowers christmas lockdown baby's first christmas luxury christmas crackers mens christmas gifts christmas tree clipart personalised christmas cards christmas songs list christmas pudding recipe christmas markets london last christmas song a christmas carol (miniseries) cast john lewis christmas christmas wreaths homebase christmas tree gavin and stacey christmas special christmas tree ideas sheffield christmas market tesco christmas jumpers nottingham christmas market real christmas trees near me christmas day 2022 personalised christmas stocking christmas cardigan last christmas movie manchester christmas market top toys for christmas 2022 christmas gift bags christmas ornaments
