I'm trying to set the elevation on my Satellite Dish to 22.8 Degrees.
Problem is that the scale on the adjustment arc goes from 20 to 90.
20 makes the dish point slightly downwards.
22.8 also makes the dish point slightly downwards.
40 makes the dish point straight ahead.
90 makes the dish point over half-way to vertical.
Please could someone explain how the recommended elevation of 22.8 relates to the Satellite Dish's elevation scale reading?
