ABSTRACT
Many practical forms of antenna are used in
aircraft and aviation-related applications. The
following are some of the most common types
(several other antennas will be introduced in later
chapters).
2.8.1 Vertical quarter-wave antennas
One of the most simple antennas to construct is
the quarter-wave antenna (also known as a
Marconi antenna). Such antennas produce an
omnidirectional radiation pattern in the horizontal
plane and radiate vertically polarised signals.
