【Xiang
Mei】It
is because of the proximity to the train station
that the spot is determined for the building.
Therefore, a lot of time and strength could be
saved from transporting those building materials
and heavy cables. Besides, around the site is a
vast tract field of paddy, which is an excellent
medium to help transmit radio waves further. All
the branches of the radio are located at the
west part of Taiwan, where an open sea lies
aside and no obstruction would get in the way of
radio waves. However, east Taiwan is surrounded
by mountains and hills, which will terribly
interfere with the transmission. |

【Xiang
Mei】Let’s
compare the wash pebbles made by the
Japanese 70 years ago with those by
ourselves on the other side. You will
feel the latter is rough and rugged on
the surface, whereas the former is
smooth and neat, which creates a huge
gap in terms of delicacy, subtlety and
quality. Some walls are covered with
marbles, which are normally break into
fragments, while wash pebbles always
appear as a whole piece and cover a wide
area, just like those on second floor. |

【Jian
You】Now,
I am going to lead you to see how enormous the
cable collectors are. |

【Teacher,
Li Jin Hang】Those
antenna towers out there look slightly different
from each other. What is the difference among
them? |
|
【Xiang
Mei】The grey
ones shaped in diamond in the front are
directional antennas, which determine the
direction in which the signals are transmitted,
and the steel towers in red and white are
omnidirectional antennas. |

【An
unidentified Lady】The
short wave is to be received with a
specific type of radio. Short waves can
be transmitted to distant places thanks
to the property of the ionosphere that
refracts short waves to ground. There
are eight branches around here, all with
omnidirectional antennas, yet
transmitters of different frequencies
