Intellisat Automatic Satellite Dish

Further to the post on maintenance of Oyster satellite dishes, I contacted Intellisat today. Manfred is overseas currently. The staff member I spoke to advised there is no specific requirement for maintenance of the Intellisat dish. He stated everything is stainless steel & fully enclosed. I guess you get what you pay for! I don't want to be climbing on the roof with silicone spray to lubricate the dish.
