Hi I'm installing my satellite inside my balcony and I'm having lots of trouble finding a signal. I have a clear line of sight and i'm pointing in the right direction. My post is plumb and i'm using a signal meter. The meter does not change as I move the antenna. Can it be that something is interfering with the signal, probably the balcony railing not as line of sight interference but more electromagnetic wise. Should I use a better quality LNB? Please help!!!!!
