Will coax splitter cause BT Vision problems

smallmaj · 17-11-2013, 16:37

Hi,

I want to use a coax splitter on the cable that goes from the aerial to the BT Vision box.

I know that some older TV and video devices cannot cope with the drop in signal power that a splitter causes.

Has anyone had a problem with BT Vision and a coax splitter?

Thanks
J

That is a question that is next to impossible to answer with any accuracy.

Whether a splitter works or not depends on several factors. The signal strength from the aerial being a major one. Then there is the type of splitter. A powered device may be needed in poor signal areas to overcome the losses of a passive splitter.

In good signal areas a passive splitter can work. Though it is always a good idea to use a good quality one with the lowest losses. Avoid the really cheap and nasty white Y shaped ones as they tend to have the highest signal loss.

If the TV or Vision box has a signal strength indicator you can gauge whether a passive or powered device is needed from that. Basically if the weakest multiplex is reading lower than 40-50% strength then you might need a powered splitter. If the weakest multiplex is reading 60% + then a passive splitter may work fine.

The only real way to tell if a passive splitter works in your installation is to try it. No-one on DS can say for certain that it will or will not work as we have no knowledge of your set-up.

You could also try splitting the signal on the way out of the box rather than the way in

Remembering that if it is a youview box to make sure you turn on rf loop through in the menu.
