Cane mast

A tubular mast is a mast made from a pipe.

It is often used in guyed shape with a circular cross section as a transmission tower, with both a use as a mast radiator as well as supporting mast for FM - and TV - antennas is possible. He has a lattice mast oppositethe advantage of a more aesthetic appearance and better protection of the cables laid in it. In many versions, it also offers weather protection when climbing the mast or for a possibly existing elevator system. A disadvantage of tubular masts is that inside the tall, hollow vertical column, moisture can condense on the cold mast walls and even rain down under certain circumstances. Further disadvantages are the higher construction costs, the higher mast weight and the increased risk of wind-related tendencies to oscillate. Against the latter, vibration dampers are sometimes built into the mast, which look like cylindrical bulges.

Guyed tubular masts are not and were not used for broadcasting purposes in all countries. Most of these masts exist in Germany, Great Britain, France, the former Soviet Union, the Czech Republic, Slovakia and Japan. They are very rare in the rest of the world.

Tubular masts for overhead line masts are mostly designed as free-standing octagonal tubular steel constructions, which do not allow internal ascent ( tubular steel mast ).

An interesting special form of guyed tubular masts are type 30107 KM transmission masts in the former Soviet Union.
