hi, i hope someone out there can help me .im trying to combine sky digital signal and saturn (telstra clear) plus signal from both vhf and uhf antenna's together.
at the moment i have sky digital plugged into my video machine via a/v leads
saturn broadband plugged into the rf in on the video
and then rf out to a 2way splitter  which feeds 2 tv's
i would like to know if i can combine all the  aerial  leads into one
i have tried to plug saturn lead into aerial/cable  input on the rear of sky decoder (lost the picture)
i have tried reversing a 2way spliiter (lost the picture also )

any suggestions would be appreciated
