Lesson 2/Learning Event 1
CALCULATE ANTENNA LENGTH
Given this lesson material, pencil, paper and without
knowledge by correctly responding to 70 percent of the
length and identifying antenna properties.
Learning Event 1:
a. The antenna is part of the electrical circuit of the
in free space at 300,000,000 meters per second.
Our antenna is not
in free space but erected over and near terrain features which affect
antenna length. For that reason, the physical length of the antenna
is shorter than the electrical length.
b. There are several factors which cause the antenna to be
As the diameter of the antenna wire increases,
the velocity or speed of the radio waves is slowed, decreasing
antenna length. See Figure 29.
