MEGATRO Roof Mounts and top structure
MEGATRO is professional and capability to enable us to supply various solutions for rooftop sites. With these solutions, you will benefit from easy access to the antenna and faster installation. They are particularly useful in urban areas where site space for a tower is not feasible, but tall buildings are available to mount antennae on. Our roof mounts to meet a variety of communication tower needs such as PCS, wireless cable, DBS, and UHF/VHS reception.
With professionally engineered construction and fabrication, you can be assured you're getting a virtually maintenance-free product built to the highest standards. And because our roof mounts are hot-DIP galvanized after fabrication, our roof mounts won't rust.
Additional features inculde:
Offer both Fixed Mounts and ballast roof mounts

MEGATRO provide roof mounts and top structure design with below requirements
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:
Feeder runway
Feeders
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.
