dish positioning?


Thinking on what someone said I was trying to figure out how to nod the dish up and down to get the best signal. In my case it needs to be very light as its manually raised. I was trying to think about a spring-loaded arrangement and to simply have a cord over a pully coming down the mast which I simply pull on the nod dish dow, releasing it will nod dish back up due to spring.

The smallest one has 2inch movement which would be more than enough but can't see it it can be nudged in and out or its either fully in or fully out. 

What do others use for nudging their dishes?
