I have a situation where all the 8 cables from my Octo LNB are used. In one of the rooms which has a single cable outlet I want to provide a second outlet which is simply designed to provide flexibility in the room layout. Only one of the two outlets would be in use at any one time.
To accomplish this I think I can split that single cable into two using this...

Will this work, and would I experience any significant loss in signal strength/quality in splitting this way?
Is there a better way of accomplishing a second outlet, keeping in mind the use I have highlighted above.?

Yes, that should work, the important thing is the pwoer pass through (which controls the LNB), and this says it does.

Will be fine as long as you are only using 1 of the outputs at a time (although, in theory, you could use the second output at the smae time, and get a quarter of the channels, but that can get complicated).

Have you thought about getting another LNB along with one of these?

With a min of 3 degrees separation I believe that holder is designed for a 2 satellite installation, not simply 2 LNBs on the same satellite. Correct?

I wouldn't have a clue myself, I've just seen the odd dish here and there that has the same.

Correct . If the op wants to use a lnb output in a different location then a simple patch box is all that's needed.

Patch box?

Or use a lnb manual switch

That should do it, thanks.

Just a follow up on the patch plate recommended by grahamlthompson, thanks graham...
I bought two of these from...

...which was the cheapest taking postage into the equation.
Plates are very good quality Labgear units.
I took one cable from the octo LNB and routed it to the plate. From the plate I ran additional cables to all the new spots where I might want an outlet, including a second cable to some existing single outlets. Now, off of an octo LNB I have the flexibility to feed 9 rooms either with twin feeds or single feeds, directly off of the LNB or via the plate.
For example, 3 rooms with twin feeds for PVR, plus 2 rooms with single feed. Or two rooms with twin feed and 4 with single. I can vary which rooms get a feed.
Worked out very well for my requirements.

BTW...you can also get an 8-way version of that plate so you can mix and match outputs as required...

Sounds to me that it is easier to split an infinitive

Explain ???

I know it ruins a joke by having to explain it but this thread is about splitting a Freesat signal - I simply said it it would be easier to split an Infinitive. e.g.the famous Star Trek phrase. English Grammar.

It's OK. I got it anyway! Anyway, certainly with one of those multi F-connector plates it would be easy to quickly swap between receivers.

Yes, I boldly went to coin a phrase.
