Thanks for pointing to that definition -- i wasn't aware of it. The confusion on the wiki seems to come from the fact that 'the terms "mast" and "tower" are often used interchangeably', as noted on Wikipedia: https://en.wikipedia.org/wiki/Radio_masts_and_towers#Mast_or_tower? That is, we have two contradictory definitions on the wiki: the engineering definition according to which a tower is freestanding and mast guyed, and the other definition according to which 'a tower is accessible and provides platforms, whereas a mast only offers ladder steps to climb it'. (Where does this latter definition come from?) To solve the contradiction we need to get rid of one of the two definitions.
