Thanks for all the help everyone. I received the antenna today and proceeded to set it up. I've gotten the antenna set up on my roof and have it connected to my 5-6 year old Sony TV. I used the leftover mount from an old DirecTV satellite that I had up there to mount the antenna along with some PVC pipe and tape. I used the pre-existing coaxial cable that was routed when the DirecTV satellite was set up to connect the new antenna to my TV. I also pointed it in approximately the 300-320 degree direction. Despite setting it up like this, I receive next to no channels.
The autoprogram feature on the TV was able to find around 20 channels, but almost all of them except for NBC are unviewable. There are a lot of channels that are like 18.1, 18.2, 18.3, etc, all of which have no signal. CBS has bad picture quality and the one local channel I really like, KTLA, is not discovered by my antenna. Only NBC works properly.
Does anyone have any tips on how I can get more channels?
Attached to this post is a picture of where I have the antenna set up and where it is pointing. North is shown in the compass in the top right.
Thanks!
