hi,i have a phillips amplified antenna hooked up to my bedroom set,works fine.But today i was going to move it over a few feet which it is mounted outside so i added some rg6 cable to the rg59 which is standard on this antenna,and i lost two of my local channels but i still have two and they are showing good,all four channels are coming from the same town.Could the rg6 cable may be robbing me of my reception? need your help
