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.
