As often happens, success stories are the fruit of the work of people who believe in what they do and who base relationships on trust and human relationships.
This also applies to the collaboration between the D4C – Monteverde Contest Team (Cape Verde, Africa CQ Zone 35) and the antenna manufacturer Momobeam.
After a brief meeting between the D4C group and Giuseppe Spano’, President and Chief Antenna Designer at Momobeam, it was agreed that work would begin to develop and manufacture a robust line of antennas suitable for the Cape Verde environment.
The meteorological conditions at D4C are extreme, as the station is located on an island in the middle of the Atlantic Ocean at 750 m ASL, with daily extreme trade winds, salt and high humidity conditions.
A series of strategic planning sessions followed to address the needs of a highly competitive contest station which included gain arrays to Europe, NA and Asia to maximize the station’s availability to all parts of the world.
The antennas that ultimately were developed, started with advanced computer simulations and prototype builds, then the performance was verified at the Momobeam antenna range.
The resulting line of high performance, highly reliable monoband yagis was impressive.
These are heavy duty, rugged products that are now available as standard products (as an option) from Momobeam!
Since March 2015, the D4C station has been fully developed to cover the HF and VHF bands and all based on Momobeam products.
As of 2022, the total number of antennas installed on the HF bands are 19 yagis and 5 verticals as per following models:
For 50Mhz we use:
All antennas have been built to the Momobeam Heavy Duty version standard to survive our harsh environment providing fantastic results!
