Aside from being used to install decoys for anti-radiation missiles, I really have no idea what other uses these towers have.
These towers are expensive, not to mention installing them on top of such a high mountain. (Avg. 5,500 m ASL)

@pir34 I didn't realize it was much bigger than I had imagined until I saw the photo taken from this angle.
To receive extremely weak signals propagating through tropospheric scattering, you need lots of antenna gain, so using larger antennas is unavoidable.

What a change, or did someone make a mistake?
