Hi Martin,

These are challenging to spot and hard to tag correctly without local 
knowledge I just discovered.


I usually find towers by seeing the shadow they cast, that is the big 
indicator to me.

Here are a few examples in the region:


If you look very carefully at the shadow you can see the microwave 
transceiver drums in the shadow. I would guess that is what helped the 
person identify this one as a "communications" tower specifically.



That one again, shows the shadow being a pretty big factor. And it also 
show a typical service road and pad. I do not know how the mapper knew 
it was a communications tower.



Shadow and microwave drums visible



Shadow and service area fenced off.



A nice big TV transmission tower.

I hope those help!
