The directionality of the array is due to the spatial relationships and the electrical feed relationships between individual antennas.

Under some circumstances where a central or common antenna is available, a community association or landlord may restrict the installation of individual antennas.

These arrays of individual antennas will in effect create one much wider, more sensitive antenna that is able to pick up the faint signals.

This design uses two or more individual antennas tuned to the same band, relying on a microprocessor in the radio to select the clearest signal.

Usually, the spatial relationship of the individual antennas also contributes to the directivity of the antenna array.

The Cyclops system would instead capitalize on our ability to connect many individual antennas to act in unison.

The multiple-axis systems generally use three individual antennas aimed in specific directions to steer the acoustic beam.

Instead, it issues individual antennas, about the size of a small electric fan, for installation on window sills.

Each unit cell incorporates an individual line-source antenna, but in the presence of all the others.

Aereo provides this service by leasing to each user an individual remote antenna.
