Information on Active Antenna
An active antenna includes electronics to optimise the
performance of the antenna. An important feature of many types
of active antenna is to allow efficient operation
across a broad frequency range, and to provide a low
noise amplifier for weak signals. The low noise amplified in
an active antenna is mounted with the antenna
itself to minimise the impact of interfering signals.
Unlike other types
of antenna, an active antenna requires its own
power supply.
