We, in association with a professional structural engineer, have developed a method of increasing the capacity of existing telecommunication monopole structures by internally fixing vertical carbon fiber strips at predetermined positions.
The system has been deployed successfully on several Monopoles in locations varying from coastal, escarpment and inland sites. We have also completed work on a camouflage monopole in an urban area.
We applied both the steel strips (40mm x 8 mm) and carbon fiber strips (120mm x 1.4mm) on the outside and had to use scaffolding.
The Existing Design capacity was 5.5m 2 of antenna area. We added 8.5m 2 capacity to the original design resulting in total capacity of 14m 2 .
Results: the client could add more antennae to the top of the tower.
On the rest of the monopoles (Kempton Park; Swart Umfolozi; Pietermaritzburg and Mossel Bay) we used carbon fiber strips exclusively and the application was on the inside only:
DE ALMEIDA (MOSSELBAY)
-Strong Wind at the coast
- 55 M HIGH MONOPOLE
- 9 M2 ADDED CAPPACITY
We have a :
- Cost effective (Average R 50,000.00 per m2 added)
- Can be designed for specific site requirements (No redundant capacity)
- Further upgrading possible after initial upgrading
- Quick installation time
- Reduced safety risks – no scaffolding
- No external sand blasting or repainting required
- removal of existing antenna not required
- No re-camouflaging
- Weather has little influence
