COMPROD FOUR CAVITY DUPLEXER FOR VHF AT A SINGLE 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.
IF ADDITIONAL CHANNEL ISOLATION IS REQUIRED THEN THE ADDITION OF TWO MORE CAVITIES
CAN PROVIDE UP TO 85 db OF CHANNEL ISOLATION.
THIS WILL STILL BE A LOT LESS $$$ THAN THE "MUCH LARGER 6.625" CAVITY SETS"*** NEEDED AT COMMERCIAL MULTI-REPEATER SITES WHICH OFTEN HAVE LOTS OF INTERMODULATION PRESENT AND REQUIRE AN EXPENSIVESET OF TOP QUALITY "PSEUDO BAND PASS DUPLEXERS".
NOTICE THAT COMPROD CAN ACHIEVE 85db OF ISOLATION AND STILL OFFER 500KHz SPACING.
THIS SIX CAVITY 4" SET WILL GIVE THE SAME PERFORMANCE
OF THE LARGER 6.625" DUPLEXER.
THIS IS HOW COMPROD CAN SAVE YOU $$$
*** SEE THE LAST PHOTO ON THIS PAGE FOR AN EXAMPLE OF A FOUR CAVITY 6.625" SET OF DUPLEXERS.
THIS SET (# 66-13-46) FROM COMPROD WILL COST >>> $2,195.00 ***
