Hey, sorted my wired and wireless network, looking at finishing off my tv network now.

In my patch cupboard I have run:
2x coax from Sky dish
1x coax from UHF
5x various coax to tv locations
3x coax labeled blue, green, red to main tv location (This was based off a signet pdf)

I have: 
1x 10MM-MST08 (link) and have the attached diagrams to figure this out (link)
1x 07MM-GM03 3-way splitter (1 in 3 out)
Has anyone had any experience installing one of these with a similar setup?

My confusion comes from the first page of the diagram (link) with the UHF to Terr port on the MST08 and the red lines coming out of it. I understand I will terminate the 2x coax from the sky dish to the ports on the side.

Any guidance, much appreciated, Cheers 

this is a slap in the face!

1x coax for FM aerial from roof?

Don't power the multiswitch with the LNB voltage fromreceivers - use a seperate power supply. (current draw is usually over what your receiver can handle

The red lines indicate RF return feeds from decoders/modulators to connect in to the TERR port. (You'll need to combine any modulated VHF/UHF feeds with the UHF aerial before going into the TERR in)

Havn't run anything from an FM aerial.

The box is powered by the Sky Dish.

Do I run a coax from the sky decoder into the splitter to combine with the UHF feed?

The levels of the RF out of old sky boxes etc is too low to normally mix into the off air RF, and at least on mums skybox has numerous spurious signals as well which were responsible for messing with DVB-T reception when mixed in till I tried all the channels almost. Needed an amplifier on the output before mixing to get it acceptable.

May have been able to mix and then amplify but the off air levels were fine to split 8 ways and then another 2 ways on a couple of runs without amplifications, whereas the sky box was so noisy it was jumping around thru the same splitters.

RF distribution had its place when people had 20" CRT's in their rooms, not 32" full HD LCD's

Have one of these lying around to use if need be (

I have figured out the cabling, hopefully get some time to terminate it all this weekend.
