FOUR CAVITY DUPLEXER FOR VHF AT A SINGLE DANIELS REPEATER SITE IN RWANDA IN 2008.
The Republic of Rwanda is a small landlocked country in the Great Lakes region of east-central Africa, bordered by Uganda, Burundi, the Democratic Republic of the Congo and Tanzania. Home to approximately 10.1 million people, Rwanda supports the densest population in continental Africa, most of whom engage in subsistence agriculture. A verdant country of fertile and hilly terrain,
the small republic bears the title "Land of a Thousand Hills".
The country has received considerable international attention on account of its 1994 genocide, in which between 800,000 and one million people were killed. Since then, Rwanda has applied for membership of the Commonwealth of Nations, and a decision on its application is expected in 2009. In 2008, Rwanda became the first country in history to elect a national legislature in which
a majority of members were women.
