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. 

or.... ebay 124219350197

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?

ps:   This one, 124267700578 has a 1inch stoke which should be adequate? I'm assuming its a dc motor, reverse the polarity on leads to get in and out?

Hi Ben
That's what I use with simple switch to reverse polarity 12vdc set your the centre to 0deg then
You have equal throw either side , it was suggested to me by G8DMU and it works very well
