Satellite Radio signal reception in North America is affected by how far south you are relative to the satellites' track. In some locations terrestrial repeaters are used to augment what would otherwise be a weak satellite radio signal. The Gulf Coast could be one of those areas with marginal satellite radio reception.
Some years ago I tried to used a Sirius Radio receiver from home, this was in South Florida. I had to return the radio as I could not receive the signal from the home location even with an optimal window exposure.
