Location show on map
Olsztyn (Pieczewo District), Poland
Date of build
The mast has a height of 360 m and is the highest object in Poland since the collapse of the mast in Konstantynów (8.08.1991). It is located on the site of a former military training ground.
It is supported by 5 floors of lashings made of steel cables with a diameter of 5 cm.
The structure is divided into 3 sections. The longest (from the ground up to the 4th floor of stays) is a lattice with an equilateral triangle cross-section. Another is a square truss and is located between the two highest levels of guy ropes. The last part placed on the top is a composite tube, inside which is a steel frame and transmitters attached to it.
Mast unlike most similar constructions does not have a fan line or ceramic insulators at the base because it is not itself a transmitting antenna in itself. It serves only as a frame, to which various transmitters, mainly television and radio, are attached at various heights.
