SLx8L and Freeview Digibox
 

Hello and good afternoon everyone
Your help please
I have a SLx8L taking a feed from a digital terrestrial aerial and
connected to a digibox (Philips DTR220).
If I connect the digibox to the aerial output on the triplex faceplate
(the main lounge output) everything is fine; but if I connect a digibox
to any of the other outputs (bedroom for example) I can only get some
channels - ITV C4 C5 et al are missing.
So the question is do I need a duplex wall plate at the end of each
output and if so what type please?
If not, do you have any other suggestions?
Many thanks
TIA
Martyn James

Are you feeding back the RF output from your STB back up to the SLx8L?
Or are you splitting the RF downlink somewhere? Have you got a FM or DAB
aerial connected?

On the triplex faceplate are you using all of the outputs. If not, you
probably need to terminate the unused outputs with 75 ohms.

When I first installed a SLx8L with the recommended triplex faceplate I
didn't use all the outputs. My Freeview box picked up all the MUXs but
the signal strength was very 'all over the place'. (on my box I can
display the signal strength for all MUXs on a single screen).
Terminating the unused outputs gave uniformity across all the MUXs, and
a higher signal strength on some.

I've got an SLX8 and use 6 outputs. The extra "full" 20db output is
terminated, the two standard unused outputs are unterminated. The outputs
serve a mixture of diplexed and triplexed face plates, and flying leads. On
the diplexed and triplexed plates not all sockets are in use, the others are
unterminated. It doesn't seem to make any difference.

I would try swapping the connections on the SLX8 so that the lounge is fed
by a different socket on the SLX8 - possibly one of the previous ones you
have had problems with. See if the problem moves with the change, if not,
try a loose run of quality cable from the SLX to the bedroom which will tell
you of the existing cable run is the problem.

It that be that your incoming signal level is marginal, and some of your
cable runs from the SLX to rooms are lossy, and others are okay.
