"When the structure is fastened with guy wires, you can map it as<br>

"When the structure is made from steel or concrete, it is not a tower,<br>
it could be a mast though" (maybe not the best example).</div></blockquote></div><br><br></div><div class="gmail_extra">yes, clearly not the best example ;-)<br></div><div class="gmail_extra">It's quite obvious that "steel and concrete" can be safely removed from the definition, as almost any structure is made of concrete or steel (or wood or masonry), and while a masonry mast likely doesn't exist (a chimney isn't a mast I think), wooden masts are probably common as well (or are they all called "pole" then, and the mast is used only in nautical context?).<br><br></div><div class="gmail_extra">Cheers,<br></div><div class="gmail_extra">Martin<br></div></div>
