2 x 'RF Out 2' combined in to 1 TV Coaxial (RG6) Distribution

[digicon]

Those are the ones to steer clear of so you have options to have RF channels on 21-30 and possibly 48-59 do not place anything on 60-69 as this is now @800mhz 4G band.

If you had a rack mount and able to distribute Cat5E all over the house i am surprised you did not go down the Cat5E/HDMI extenders would have upped your budget slightly but you would have had HD in all rooms that where equipped with Cat5E.

Glad its all sorted

That was an option, but If I did it I would use up all Cat5e sockets as I only have 2 in each room, The HDMI to Cat5 converters need 2 x Cat5e cables, If I had of installed cat6 then I could have got away with just the 1 cable.

Something for me to think about for the next house #

I have 1 channel stored on Channel 21 already
Think I'll try tune the other channel from the other group of channel's between 48-59

Thanks again

Most of the decent HDMI Cat extenders will now work over a single Cat5e and transfer over the IR part for you as well

[PJD]

I didn't know they done it over a single Cat5e, when I first set up this system 2 years ago, they could only be sent over dual Cat5e, will bear it in mind maybe make some adjustments at a later date

I have had my replacement O/I link sent out,
I've set it all up, reprogrammed the channels
Channel 21 for Sat still & changed the channel 52 to Channel 58 for Sky (Done this to get a clearer picture)
Both channels are clear, I am able to change both the channels on Sky & Sat Boxes from all the rooms in the house, Just need to purchase some more remotes.

The only problem I am experiencing is when the Freeview cable is connected to the 'RF In' I get interference on all the channels, It took me about 3 hours to realize what the issue was, upon disconnecting the Freeview coax from the 'RF In' the picture became clear.

I have done a bit of googling and found that I may need a "Variable Attenuator" to connect inline with the freeview coax to stop the interference, is this right? they are around ?5 each on Ebay would be great if it resolved my issue, its just weird how I am now getting interference when I didn't before
I have double checked all the cables and connections even replaced them to no avail.
I also tried to just solely wire in the I/O link and solely wire in the RF transmitter, still got interference until I disconnected the Freeview from the 'RF In'

Also if anybody else is going to do a similar set up for them selves they need to wire them in this order as the way I had it before I could not change the channels on the Sat box.

Freeview (From Roof Aerial) >> To >> 'RF In' (On I/O link, (Connected to Sky HD box))
'RF 2 Out' (I/O Link) >> To >> 'RF In' (On RF Modulator from Sat box)
'RF 2 Out' (RF Modulator) >> To >> Distribution in loft
Distribution in loft >> To >> each TV with A magic eye connected.

Wiring it this way (In to I/O Link first) enables full control of both the Sky and Sat box through the magic eyes
Wiring it the other way (In to RF modulator first) stops the Inferred signal from getting to the RF modulator fore some reason.

I hope it helps other people.

You could try a bandpass filter as it appears that you may still be getting some form of interference from one or two freeview frequency's, as you are probably aware your aerial could be picking up another main transmitter or even a relay that could be within a 70 mile radius.

Try a bandpass filter that allows all your main transmitter frequency's through and attach it to the end of your Freeview aerial feed before it goes into the I/O link

[PJD]

Is there any particular type or frequency that you'd recommend I should get?

[digicon]

no particular brand but they come in different frequency ranges so just make sure you get one that does not block any of your main transmitter ones

Groups are as follows:

A: CH's 21-37 B: CH's 34-53 C/D: CH's 48-68 E: CH's 35-68 K: CH's 21-48

I am using channels 21 & 58, does that mean I will need to install 2 together?

No! your at the wrong end of the stick a band pass filter suppresses Freeview transmitter signals so if you chose a Band A filter for example you would not get ant Freeview channels on frequency range 21-37 so you could put an RF channel in that range without fear of any co-channel interference from the freeview spectrum

[PJD]

Yes I see what you mean, but my RF channels stored are 21 & 58 which both are being interfered with the freeview connected up,
Both these channels are stored in different bands which is why I thought I might need 2 different filters?

[digicon]

you only need 1 filter and then you can send both RF channels in the frequency range that the band pass filter blocks out

[PJD]

Oh I see, so change both the channels to be stored in say band A so keep channel 21 and maybe swap channel 58 to channel 30 say and all should be good ?

Yes thats the general idea obviously make sure you get a filter that does not infringe on any of your freeview spectrum for your area

[PJD]

So I can't just go out and buy any old band, I have to find the 1 which has least impact on my freeview, nothing is ever simple is it
