The lower part consists of three 20ft galvanised steel pipes, welded together to form a Tripod, supported by three stainless steel guy wires. The tower stands on rubber engine mountings to reduce any vibration which is transmitted to the building...
The upper 20ft section is just a steel pipe supported by a further six guy wires. The upper section can be easily lowered / raised by hand while standing at the top of the first section.
