Comparisions

From a total of 7 different pole sections a combination of various lengths and strengths is achieved. A typical strength combination of a 16m pole is depicted. The larger diameter combination has higher strength.

Categories	Obelisk Poles	Conventional Poles
Weight	Light weight - 20m Monopole weighs just less than 400 Kgs, ideal for roof tops in case of earth quake - less risk of damage to property.	Weight approx. 4 tons plus, increased costs and energy requirement. High risk to Life in case of Earthquake.
Corrosion	Corrosion resistant: long maintenance free life of over 30 years in coastal & saline atmosphere.	Corrodes severely in coastal area inspite of repeated painting, requires regular painting costs. Life span can be as low as 5 years in some cases
Transportation Cost	Low transportation cost - 6 towers in one container	Transportation cost High - One tower in one container
Installation	Light duty crane required to install, Installation time is half of Metal towers.	Heavy crane required to handle Metal. High labour cost for assembly and Double Installation Cost
Handling	Single section of pole can be manually lifted for ground handling.	Requires crane for ground handling
Carbon emission	30% lower carbon footprint v/s steel towers. The manufacturing process releases no volatile compounds (VOCs) or hazardous pollutants	High carbon emission foot print

Obelisk poles are 6 - 8
times lighter than steel poles.
