c oax cable splitter with built in switch

Can somebody please explain how these work. Is it possible by using the switch to get the full existing signal strength through only one of the ports ?

Perhaps you need to tell us the make and model of the item in question?

Maplins advertise one but make or model not mentioned

A link to the Maplin item then?

A passive/unpowered splitter will certainly degrade the signal to each output. A powered splitter/booster will be better in that regard. What has thrown me is that I have never seen a co-ax splitter with a switch?

Two different animals

A splitter has one input and multiple outputs that are active at all times.

A switch has one input and multiple outputs but only one is active at any one time. As a result there is little effect on the signal strength.

Two way one here

Ignore the fact that it says satellite, it's just a rf switch that has dc pass on one port to allow lnb control. It will work fine at UHF frequencies.

as said above there are 2 different sorts of splitters. the cheaper resistive type being higher loss. the wilkinson being better. but depends what u want it for. if a digital signal then loss is not important provided u stay above the "digital cliff".

most things like that at farnell components. url : cpc.co.uk. use search keywords then scroll through the list that appears for nearest item you want ......
