Good evening, We recently decided to ditch cable as we only seem to watch netflix anyways. It would however be nice to be able to view local channels. So... I purchased a Philips outdoor 18db antenna to stick on an old antenna mount on the gable of our house. The antenna model number is SDV8622t/27 To make a very long three day story short it will not work on the roof or in the attic. tried amp/ no amp. brand spanking new rg6 quad cable, mounting two feet above roof ridge. Every thing i could think of. As a last ditch effort i hooked it up a ratty old 50 foot piece of coax and literally threw it into the middle of the front yard. low and behold all of the channels i am supposed to be able to get. So what is the trick to get an antenna to work on a roof? I normally do not give up easily but antennas are totally foreign to me. any help would be appreciated. tv fool report = not allowed to post but my zip is 43551 I do have steel siding on the house as well as the gable. but the antenna was mounted about 1.5 foot above the peak. Thank you all for your time. ps, at this point cost is no longer an issue but kicking this antennas but is.
