What is the gain on your antenna if it's over 5 DBI It's probably just completely missing you. You should really be using 3 DBI or less if you do not know the direction that the signal is going to be coming from. As an example, you would not really be able to easily talk to a plane with a 10 DBI antenna because the plane would be above the radiation pattern of the antenna. But you would be able to talk to the plane with a 3 DBI antenna.
