HEIGHT OF ANTENNA ON THE SOIL FOR READING OF THE NOISE
ABSTRACT
The study of absorption of radiation from the Sun is highly strategic for Brazil. The
conditions of the layers of the ionosphere has a significant effect on communications in
high-frequency and low frequency, among others, may interfere with radio systems. In high
and low latitudes, depending on solar activity, high-energy particles and photons can
cause sudden changes in ionic conditions, among them the sudden closure of the
propagation of radio.
The reading from background noise at different frequencies, in monoband receptors, may
indicate changes in atmospheric electricity, can also show significant changes at the Amas
(South Atlantic Magnetic Anomaly).
In Paula Freitas City, Paraná, was built by IAE (Instituto de Aeronáutica e
Espaço), Campus de Pesquisas Geofísicas Major Edsel de Freitas Coutinho. The campus
is at the limit of the Epicenter of the South Atlantic Magnetic Anomaly, and moves slowly
westward.
This work is a brief description of the importance of the height of the antennae to examine
the background noise.
