Is there a maximum length of RG6 you can have from the client box to the SWM splitter?
I run 50 feet from dish to swim. 170 feet through splitters in some places from swim to boxes. No issues. Clients and genies.
Thanks for your input. The run in question will be between 150 and 160 from a c41 to the splitter. Also the run to the dish is pretty close to 200 feet, but I have never had a problem with longer runs from the dish. inkahauts, your comment makes me feel a little better already.
If you're having issues, go with RG11. It's good for 400+ft.
I've done a lot of research on this. 150 feet is the number I feel most comfortable with, but if you use the smallest possible splitter you can go further.
a typical SWM LNB outputs -30dbm (some may be higher). there is about 10db loss for every 100 feet of RG6. a receiver or client "likes" to see at the very least -60dbm at the satellite input. so with these numbers
-30dbm from LNB
20dbm loss from dish to splitter
16dbm loss from splitter to the client
at the receiver/client you will have about -66dbm which is too low. and this is not including fittings, ground blocks.
