What’s the reason for not allowing a Sky dish ie.listed building, conservation area, Apartment block?
I worked on several new build housing estates when I was a Sky engineer and it was quite common for the developers to state in the particulars that no Sky dishes could be fitted to the front elevation of the property.
Unsurprisingly quite often the line of sight for the dish meant they needed to be located on the front.
And again unsurprisingly the owners decided to ignore what the developers stated and we fitted the dishes anyway and there still there now.
Might be worth enquiring what the issue with them is.
