I am a having troubles with this in every house I have done this with. I have been told you can run a splitter off of a tap and it will work fine however everytime I have done this it dose not work fine. The two joeys off of the splitter will say switching from HD to SD and well as partial signal loss and other errors. The hopper also connected the tap with the splitter acts up. As soon as I remove the splitter from the tap and disconnect one of the joeys the system works fine. I have even tried switching the joeys to rule out a bad joey but the system works just as it should. Then I plug in the splitter back in and the system starts acting up again. This has done this on five houses now and the only way I have been able to solve it is to fish another line into the house and not use a tap at all. This last house I was an is using 2 hoppers and 3 joeys. There are only two rg6 cables running into the house and the tap without the splitter works fine however the splitter/tap side does not. Again as soon as the splitter is removed the system works fine minus one joey can not be used. We use holland hfs-2d 2-way splitter 5-2150mhz. Is anyone else having this trouble?
