I'm going to hijack Bricktop's thread to see if I can get an answer to something that's been intriguing me for years. What is this?

They're all over the damn landscape, seeming to mark trails across the fields. Here is a representative view - you can see two easily, and the third if you look carefully.

In this case the row seems to follow the river (the Lyne in this case) but the first post is by the roadside where the line seems to take off across the hills. I've seen new ones appear where there were none before, and I've seen old and faded ones replaced.
Nobody I've spoken to has anything more than idle speculation. They look as if they're markers for an aircraft of some sort (a helicopter?) to be able to follow the line of something, but what? Someone said gas main, but there is no gas main there. Electricity main? More plausible, but the way it takes off up the hill is strange if it was that.
My guess was markers to facilitate aerial mapping, but the odd thing is that they're barely visible at all in either the OS or the Google aerial views. You can spot one that you know is there, but if you didn't, it would just look like yet another sheep. And despite them being so obvious from ground level, they are not marked on the OS maps.
Anyone know what they are?
