Connecting a vu plus solo to a sly hd

[jdunlo]

As the title says I'm attempting to connect the 2 receivers .setup as follows
Vu receiver output via coax to aeriel in on sky HD box. The n sky HD box rf1 output to 1 in 8 out splitter. After a rescan of the TV's I can pick up the sky HD box and get a vague reception from the vu receiver. When I put the sky box on standby the vu picture is then visible and clear. Anyone elaborate on what my next move is or has anyone got a similar setup.
As always thanks in advance. Hope this is in the correct section

change the vu output channel, to different frequency. 3,5,7 clash.

Thanks for the reply mate. At the risk of being really stupid how do I change the frequency on the vu. Again thanks for your input

The VU does not have RF frequency output so cannot be changed you need Triax Tri link

Thanks satpaul. So if I purchase one of those that will solve my problems. Excellent stuff
