Introduction

Towers can be classified into four categories which are Monopole, Lattice(Self Standing), Guyed or StealthAntenna Tower Masts are structures made of Steel Hollow sections or Lattice Type placed on top of skyscrapers which are used to fix the Telecommunication, TV broadcasting antennas(UHF or VHF) and Radio broadcasting antennas

Design Concepts

To design an antenna mast first we should identify the requirements that is the number of broadcasters to be placed, type of broadcasting and strengthDesigning the transmission antennas according to the requirementsMast designer will design the antenna tower mast considering the parameters(Minimum Height, Section size and shape required) from antenna designer and structural loads :- Dead and Wind(Predominant)
