The installation of messenger cable generally presents no significant problems. However, in extremely cold weather conditions (below - 20°C or - 4°F), Belden recommends the use of the scissors method for the separation of the messenger wire from the cable. The scissors method has been shown to create the least amount of stress. It is important, however, that you use a continuous force as you separate the messenger from the drop cable.

Conclusion

In aerial installation, the maximum breaking strength and elongation characteristics of the coaxial cable determine the cable's reliability. These factors are dependent upon the characteristics of the material used for the manufacture of the messenger wire.

The messenger wire used in Belden broadband aerial cables is a high tensile strength galvanized steel. This gives Belden messenger cables a high maximum breaking strength, an important consideration in northern climates where ice loading can be substantial. Furthermore, these cables also exhibit low elongation. This is desirable in that an over - stressed Belden cable will break rather than stretch. Stretched cables experience difficult - to - troubleshoot transmission problems.
