The old AMPS system antennae are pretty much omnidirectional, and those are the
types of phones the FCC regulation prohibits. The PCS antennae are more
directional and don't seem to pick up signals from above very well. Some PCS
phones use the AMPS network as a backup and will work pretty well in the air.
