Training
Evaluating Multiple Outlet Requirements, Part 3
By the NCTI

This months installment continues a series on evaluating the requirements for multiple outlets. The material is adapted from a lesson in NCTIs Installer Course. © NCTI.

The previous installments in this series provided approximate worst-case signal loss values for two-, three-, four- and eight-way splitters that can be used to easily make rough estimates in the field. This installment deals with combining splitters to customize the number of output ports.

To provide broadband signals to between four and eight cable outlets, a variety of splitter combinations can be used. Five, six and seven output ports can be easily achieved by connecting together different combinations of two-, three- and four-way splitters with a short coaxial cable jumper(s), as shown in the accompanying figures.

Some cable systems provide an eight-way splitter and terminate the unused ports. However, the eight-way splitter does cause more signal loss for some of the output ports, compared to some combinations. TB

• Combining two-way splitter with four-way splitter/Combining balanced and unbalanced three-way splitters
• Combining various splitters to provide six output ports
• Combining two-say, balanced three-way and four-way splitters to provide seven output ports

The next installment will provide information on using auxiliary house amplifiers.
