diplexing a motor sat dish

Anchises

Would combining/decombining a SAT cable and DTT cable , with diplexers, to provide only one feed cable, be possible if the sat dish was also motor driven/adjustable ?

Don't see why not. :cool:

Sorry - I did not fully decsribe the issue in the first question

The issue is that the outside diplexor (combiner) is a mastamp also and it has a power supply. (Televes 5350)

I think the issue I'm concerned with is the placement of the power supply for the mast amp/diplexor.

Will the power to the mast amp get there through the inner diplexor (splitter) from the DTT cable at the TV where the power supply is located. I have the impression that diplexors allow power back through the SAT side only. Diplexor shows 'power-pass' on one leg only (SAT path).

Those Televes amps can be powered by the sat. receiver, see here.

Thanks for pointing that out. I'd looked at that spec sheet several times and never spotted that it indicated DC being provided by the STB.

Is it true that *all* STB would do that ?

Any STB that doesn't should be in a museum . . .

All hooked up and working.
Thanks for the help.

Now a further step .......

I'm currently driving a combo box with this setup. Finally only one cable.

Whats the best way to get the DTT signal from the same antenna to another set in the next room.
Looks like I need to split it out of the present arrangement at some point.

==A==> Sat + UHF in ---B--> single cable --B----> Sat + UHF out ===C=>


Where is it possible to split, A, B, C ? On the single cable (B) would be perfect since it physically passes the other (2nd.TV). Is that possible and what kind of splitter ? I don't need to interfere with the SAT feed to the 2nd TV, - it has it's own sat dish input.

If I split at the UHF out point (C) , I will end up with two cables again (well -for some of the way!!) to get back to the other TV.

I remember seeing on the forum a thread with multiple diagrams about this subject and I just cannot find it again

I would just use the 'aerial out' from the combo box although the diagram in the Televes amplifier pdf seems to show some kind of tap-off wallplates.

Where you'd get these is another matter & hardly worth the bother for 1 outlet.

I could do that, it's a simple pass through, and feed it to the other room's DTT STB, but that means another cable....

Oh well - I suppoe that's th way to go
