Nice pics.

At the airports they have the horizontal one then a vertical one, they work in tandem to give the position and glideslope for fully automatic landing (think they call it a cat 3 landing), this might be what the vertical one's for here all though if it's not at an airport they're unlikely to need glideslope indication.

Wise move not climbing it, don't think it'd be just a ticking off getting busted on that.
