Yagi efficiency
Does anyone know why the efficiency of the Stanford Big Dish (150 feet) is only 35% on 1420MHz, compared to 55% on 150 and 400MHz? http://www-star.stanford.edu/rsg/bigdish.php --Zack Lau W1VT More than likely, mesh in the reflector is too big and parabolic perfection is poorer at the higher frequency W4ZCB |
