Re: Is LNB Cable Length Significant?

Hello and welcome!

All coax (or cables as you said) has loss. The longer the coax the more the loss. Loss means that if you have 100% signal strength / quality at on one end of the coax you will have less signal strength / quality on the other end. The longer the coax the greater the loss.

In your question, as long as the length of the coax between the LNB and Switch (Diseq) doesn't have any extra coiled up, it shouldn't make much of a difference. Where the difference would really come in is the total length of the run between the LNB and the box. This relates to creativegenius' comment about having under a 106 feet coax run to your box. I have my switch mounted at the dish so I only have to run one coax into the house. You could have multiple runs of coax into the house and have your switch inside but that means more coax and more money for the coax.

If you're really interested in coax loss do a google search for "coax loss" and you should find some information. Also, make sure you are using RG-6 coax for your runs. That has the best signal to loss ratio for this application.

Hope that helps answer your question.
