Tubular tower appeared year 2001 in China. The main pier is made from tubular, auxiliary part made from pipe and angel steel.
The advantage of tubular tower:
1. Reduce the weight by 10%–20%
2. Reduce the wind press of the tower
3. Larger 20% rotation radius than angel tower.
4. Larger load capacity than angel tower.
5. Reduce 10%–20% material
6. Shorten preiod install
7. Structure diversification
The shortage:
1. More complex structure connection
2. Slower efficiency in production

how do telecommunication towers work
telecommunication tower consists of antennas that both transmit and receive signals from mobile phones. After receiving signal from a mobile phone, the cell phone tower then transmits the signals to a “switching center” – a telephone exchange for mobile phones. Here the call is connected either to another mobile phone or to telephone network.
