There are occasions when cell site analysis may require climbing the Mast. You really do have to have a head for heights and here is one video presenting the more extreme end of the heights that Mast climbing involves.
The video also holds some useful observations relevant to cell site identification, which is useful when considering the mini course I am running on Cell Site Identification:
Mini Course in Cell Site Identification (Pt3.s2)
Mini Course in Cell Site Identification (Pt3.s1)
