MEGATRO RADIO TOWERS AND MAST
MEGATRO is the professional design and manufacturer for every type of Radio tower and mast. There are two types of radio tower, small and large. In general the large radio tower often located and install on mountain. Radio masts and towers are, typically, tall structures designed to support antennas (also known as aerials) for telecommunications and broadcasting, including television. They are among the tallest man-made structures.
Radio masts and towers also belong to telecom tower, which mailed used for broadcasting and television network system. MEGATRO can provide every type of radio mast and towers with different type and technical requirements. Radio masts and towers systems can accommodate a variety of disc with network parts.
There are many types of radio towers according to their shape and application. In general we often consider below some data during design
1 wind speed
2 tower loading
3 earthquake and terrain type
4 tower foot span and others
Among of our radio tower, some are bottom and top smaller section and middle section larger, sometimes it is guyed by stay wire to support total structure to stand extra loading.
General Design Criteria
Radio and Mast will be designed based on GB, BS 8100, TIA/EIA-222-G-2006, IS 802 & IS875 or equivalent international standards.
MEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered.
