I've been racking my brain and I can't seem to think of an adjective that means "firmly held aloft". For example, a weathercock may be firmly held aloft at the top of a pole. A sign may be firmly held aloft at the top of a scaffold. A TV aerial may be firmly held aloft at the top of a house's ceiling. I'd like a single adjective for this (for brevity), so I can say something like:
I noticed the [firmly-held-aloft] weathercock on the church.
He pulled himself up by the [firmly-held-aloft] handlebars.
You could clearly see the time on the [firmly-held-aloft] clock.
I guess it's kind of the antonym of "dangling". Can anyone think of any such adjectives?
