DAB Band 3 Yagi Antenna
(2011-04-25) PE1ITR
8 elements 204MHz Yagi
This design is based on a YU7EF yagi antenna design.
I calculated the values for the 204MHz part of band 3 and simulated (with 4nec2) the result.
Bandwidth: 183 - 210MHz. This covers DAB channel 6B (183MHz), 6C, 6D, 7A, 7B, 7C, 7D, 8A, 8B, 8C, 8D, 9A, 9B, 9C, 9D (208.064MHz) and 10A.
This yagi is build in januari 2007.
