An effective 5 issues (free space 8,5 dBD gain) placed 9 m over the ground will have 13,06 dBD get within sixteen stages. During the 7 degree a similar yagi however produces 9,52dBD. A little 3 factors yagi (free-space 6dBD obtain)commonly produce the same signal (nine,6dBD) at the eight amounts with a peak of 13 meters.
