Megatro NTB guyed mast Guyed Masts are low cost solutions for mounting antennas at a height for telecommunication and broadcasting. MEGATROGuyed Mast Telecom Tower are designed and developed to receives assistance from guy lines. These are especially used in telecom tower in form of either supporting aerials at the top or by using the whole structure as an antenna. For all types of wires aerials including VLF, MF, LF and others, these masts are perfect. For wires aerials, these mast structures require to be installed against ground. Guyed Masts are low cost solutions for mounting antennas at a height. But the disadvantage with guyed masts are the space required is very high. The sway of the antenna is high. Some telecom guyed tower & mast are towers that have guy wires, which are tensioned cables used to stabilize the tower. While one end of the cables is attached to the top of the structure, the other end is tied to the base of the structure. Since these guy wires are tensioned and spread around the base of the main structure itself, guyed towers have special requirements for their construction.
MEGATRO guyed tower &mast also fabricated by solid steel pipe or angel steel, after fabrication all towers are delivered to the galvanizing facility to be Hot Dip Galvanized. Towers are processed through the facility by Caustic Cleaning, Pickling, and then Fluxing. These strict procedures insure years of maintenance free towers.

Design Requirements and Basic of Design MEGATRO TOWERS will guarantee the overall safety of the tower. MEGATRO TOWERS will submit design calculation report for member design of tower and overall structural stability of the structure, which is signed by a charted structural Engineer.
MEGATRO will supply the skeleton to scale, showing the assembly of the structures, the antenna mounting levels, other detail drawings etc.
The calculation method to be adopted for tower design will be decided by MEGATRO TOWERS with the consent of the client.
All materials will comply with British Standard (hereinafter called BS), Japanese Industrial Standard (hereinafter called JIS) or equivalent standards. The permissible stress of the materials will comply with BS, standard by Architectural Institute of Japan (hereinafter call AIJ) or equivalent. The standards adopted for all materials will be stated separately.
General Design Criteria
Mast will be designed based on GB, BS 8100, TIA/EIA-222-G-2006, IS 802 & IS875 or equivalent international standards.
The wind loading on the tower and antennas mounted on it will withstand a ground level wind velocity of 140 Km/h and survival speed of 180 Km/h including with height in accordance with latest BSI CP3: Chapter V: Part 2: British Standard (BS)
Antenna that will be considered when it calculates wind areas will be Six GSM antennas, Two each 600 mm diameter microwave dishes & one 1.2m Ø Microwave plus all the feeders for GSM and MW antennas.
Allowance will be given to the effective windage area of the following:
Platforms and guard rails
Ladder and ladder guards MEGATRO submit the complete data showing the drag factor from various angles of wind on the antenna offered.
