Some bit of advice as you bring it apart...if my experience this weekend is anything to go by; Please first grease all the rusty nuts and bolts before you loosen them. I had a rusted bolt (on the feedhorn of a Eurostar cband dish) first refuse to come out using a ring spanner... and thinking more force was required, I brought in my dewalt cordless wrench to finish the job. Lo and behold, the damn thing snapped leaving a portion inside the hole which I have yet to figure out how to remove. Apply a bit of grease on the others easily nudged them off.
