Ya, that is kind of what I had in mind. It is a good question that was
asked, I have been trying to think of some more features that could use
some short example guides and towers are perfect for that and are needed.
Cheers,

We could make a quick tracing guide for these towers. Just need a few
clipped screenshots of the imagery, and help text.
Would put it together in something like this:

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.

A nice big TV transmission tower.
I hope those help!
