and it would be helpful to give her PostCode in any further posts
(there's no need to provide the full PostCode - the first part should
suffice for urban areas but may need more of the code in rural areas
where PostCodes tend to cover much larger areas.)

Even in London just the first part of the post code could mislead
terribly. There are such things as tower blocks which cast long
shadows. And even some hills.

IMLE there are even some hills in Suffolk which can militate for a
longer mast.
