154
YAGI 3 elements- Example for F = 145 MHz2.07m, spacings = 2.07x0.25 = 51.7 cm, reflector fed 151/F = 1.04m, elements alimentes 143/F= 98.6 cm 2 times 49.3cm, director = 137 / F 0.945mm, or a Boom of 1.05m, impedence = 50 ohms, gain = 7 DBD, RAV-AR = 20 DB
Yagi 9 elements 144 Mhz- The first director can be moved forward or backward to search for the best ROS
Yagi Ufh 18 element- Boom in aluminum of 2 / 2mm tv length 2.80 m,the parasitic elements may be isolated or not indifferently
2 x 5 Element Yagi array for 144MHz- A 2 x 5 antenna may have similar basic gain to say a well made 10 element long yagi but with slightly different distribution of azimuth and altitude
