3.4.5 Vertical Antennas
A vertical antenna may be
connected to the SG-211 in a
number of ways. Vertical
antennas require an RF
Ground system to function
properly, but this may be
incorporated into the design
of the antenna itself.
A typical vertical antenna is
the GROUND PLANE that
includes radials in the
design. This, and many other vertical antennas use an SO-
239 connector or equivalent to feed the antenna. This type
of antenna can be connected directly to the SG-239 or via
a pigtail as shown below.
Any vertical antenna fed with Coaxial cable can be
connected in this way.
