That is an incredible view.
Despite having visited many or even most high places in this part of the country multiple times (Gibbet Hill, Black Down, Butser Hill, Walbury Hill, etc), I've (almost*) never been to this one.
(*well actually I have been, once, but it was around 5pm in early-mid November and consequently the light level wasn't great. I had intended to get there earlier but had encountered delays).
If we're talking about the low hills roughly NE of Ash and NW of Normandy, that was, I think, a long time ago. I'm fairly sure they had gone by some point in the 80s though thinking about it I think I have vague memories of masts there in the early, possibly mid-80s. Not sure. The only transmitter I can think of currently in that area is the huge one near Old Dean Estate in Camberley, which is visible from a long way away.
The memories I have are of viewing the area from high ground around Guildford, from a distance. I first used the 20 bus from Guildford to Aldershot around 1988, and was fairly sure I didn't get a close-up view of them, suggested they had gone by this time.
Which direction and how far? The most obvious one is the Old Dean one, near Camberley, which would perhaps be 5-10 miles to the north or northeast.

If it's a taller, thinner one it could be Hannington, near Basingstoke, or possibly Bexley Hill, near Midhurst.
