The interior of Galicia is characterized by its hilly landscape, although mountain ranges rise to 2,000 m (6,600 ft) in the east and south. The coastal areas are mostly an alternate series of rias (submerged valleys where the sea penetrates tens of kilometres inland) and cliffs. The climate of Galicia is temperate and rainy, but it is also markedly drier in the summer, being usually classified as Oceanic in the west and north, and Mediterranean in the southeast. Its topographic and climatic conditions have made animal husbandry and farming the primary source of Galicia's wealth for most of its history. With the exception of shipbuilding and food processing, Galicia was largely a semi-subsistence farming and fishing economy and did not experience significant industrialization until after the mid-20th century. In 2012, the gross domestic product at purchasing power parity was 56,000 million, with a nominal GDP per capita of 20,700. The population is largely concentrated in two coastal areas: from Ferrol to A Coruna in the northwest and from Pontevedra to Vigo in the southwest. To a lesser extent, there are smaller populations around the interior cities of Lugo, Ourense and Santiago de Compostela. The political capital is Santiago de Compostela, in the province of A Coruna. Vigo, in the province of Pontevedra, is the most populous municipality with 294,997 (2014), while A Coruna is the most populous city with 215.227 (2014).
What have been its two primary sources of wealth?
animal husbandry and farming

Both the vertical and dipole antennas are simple in construction and relatively inexpensive. The dipole antenna, which is the basis for most antenna designs, is a balanced component, with equal but opposite voltages and currents applied at its two terminals through a balanced transmission line (or to a coaxial transmission line through a so-called balun). The vertical antenna, on the other hand, is a monopole antenna. It is typically connected to the inner conductor of a coaxial transmission line (or a matching network); the shield of the transmission line is connected to ground. In this way, the ground (or any large conductive surface) plays the role of the second conductor of a dipole, thereby forming a complete circuit. Since monopole antennas rely on a conductive ground, a so-called grounding structure may be employed to provide a better ground contact to the earth or which itself acts as a ground plane to perform that function regardless of (or in absence of) an actual contact with the earth.
Are basic antennas expensive?
relatively inexpensive

The major roles of construction and of services (government, communications, banking and finance, food production, entertainment, and legal services) in Brasilia's economy reflect the city's status as a governmental rather than an industrial center. Industries connected with construction, food processing, and furnishings are important, as are those associated with publishing, printing, and computer software. GDP is divided in Public Administration 54.8%, Services 28.7%, Industry 10.2%, Commerce 6.1%, Agribusiness 0.2%.
How much of Brasilia's GDP is from Agribusiness?
