anyone heard of Satellite box feeds causing problems with normal tv Aerial feeds ?

is it possible that your sat feed from lnb is also joined with your aerial via one feed cable like a sat and terrestrial combiner?

I dont know mate, I didnt change anything, only way it works on the normal digital TV aerial channels as we call council telly nowdays,

, now is if I was to leave the vu box on 24/7 which I never had to do before, it was always on normal standby mode when not in use before now, I cant understand it at all.

I just wonder if it could be somehow related to this, cause its funny how all this happened round about the same time >>> http://www.digital-kaos.co.uk/forums...eding-replaced

i would imagine a voltage is coming out of box powering on your aerial?

**Hadron** · 1 December, 2016, 11:10

Does the aerial amplifier in the attic have it's own power supply, or is it the type that needs the power to be supplied by the coax cable?

If it's the latter, then it may be that the 9v supply from the sky+ box rf out has been switched off somehow. You can check by looking at the service menu. Don't know if it's the same for all boxes, but on mine you press the "services" button, press 001, press"select". This should take you to services setup. Scroll along to RF out. RF outlet power supply should be set to on. If it's not, then turn it on & press green to save settings. Your box might even have an actual switch on the back that turns the 9v on or off.

I think the power is only applied to RF socket 2, so make sure RF2 is the one that connects to the wall socket for the upstairs TV.

Don't know why the VU box should have any influence with your terrestrial TV though. Unless the aerial amplifier gets it's power from the LNB voltage, which seems unlikely.

Thanks for your comments guys, I hope I can explain a bit better, for years and years its all worked super fine the way it was.

There are two Satellite feeds that come into the house via the attic from that Sat dish LNB.

There is also a normal digital terrestrial tv aerial feed that comes into the house via the attic too, the last I seen it in the attic was years ago and seen what looked like an tv aerial booster with its own electric supply & plug and a light was on showing it was powered, I can only assume that was for the tv aerial as I dont think you can use or get such devices for satellite feeds but I don't have a clue about that, I know you can get them for tv aerial cables though (tv aerial multi splitter amplifier).

All these years the Very Old Sky+ Amstrad DRX280 box has always had 3 x RF feeds plugged into it (and the power has always been on to the box but its always been on standby, there has never been a Satellite feed plugged into it apart from the single year I subscribed to sky

And then all these past years everything has stayed the same way, all RF cables are still in the old SKY+ box, 2 x RF outputs and 1 x RF input on the the sky+ box (see the random image I found on the internet, I marked the RF sockets in red).
On the wall in the living room there are 1xRF input and 1x RF output sockets, so one of the outputs from the Sky box goes to the wall input socket and the other output from the sky box goes to the living room tv, then you have the output socket from the wall which plugs into the input socket on the sky box, think I explained that in the right order, phewww LOL

After I stopped subscribing to sky away back in the very old days (1 year sub), I had Virgin Cable for a few years and then onto the VU+DUO satellite box right up to present day like I said.
I have always had one single satellite feed going into one tuner on the VU box and for the missus she likes to have the other feed plugged into freesat for
ease of use (the freesat is actually built into the tv, its a Panasonic Tv, but anyways, same Idea really as saying a freesat box I guess).

Everything has always worked fine for years and years and nothing has changed with any of the cabling or nothing, YET, the other day out of the blue I noticed that there was no terrestrial TV on the bedroom tv and I checked the living room too and no terrestrial TV on that either, so like I already mentioned, I was scratching my head

thinking wtf is wrong man !

, the VU box was sitting on normal standby mode as usual and I switched it on and as if by magic all the tv's in the house got their terrestrial tv channels showing, then put the VU back onto standby and all the other terrestrial tv channels went off on all the tvs, so I just left the VU on for the time being while I thought about it and posted this in here the other day etc

I checked all the cabling etc, everything is still the same, and now all I can do is plug the Satellite feed into the golden oldie Sky+ box and leave it on standby and then all tv's still get their terrestrial tv channels, thats the only way its going to work.

So has anyone now got a clue what could be happening here that I have explained it a little better (I hope, Lol*)

I am hoping that when I get my VU box repaired in a few days then I will be able to go back to plugging my sat feed into it as I will kind of be stuck between a rock and hard place, I.E - with or without Terrestrial TV channels in the bedroom etc, hmmm.

I still cannot for the life of me figure it out at all man, do you think I should call in the aerial/Sat Dish repair guy or is this to do with a box or something like that, I just dont have a scooby doo what the heck could be causing it at all, does anyone though, thats the thing

rethinking about amstrad rf out one is for sat and the other would be aerial terrestrial and both going to attic for distribution elsewhere.
unsure how the vu would work with no rf.

yeah mate, I know, and it always did too (the VU), well until now I mean.

Thats how I said in earlier post, do you think there is the slightest possibilty it could be to do with this issue as it all seemed to happen round about the same time ?? >>>> http://www.digital-kaos.co.uk/forums...eding-replaced

**Saltire** · 3 December, 2016, 14:05

any aerial installers on this website that do the job as their daily thing etc ?

Just trying to find the answer to this, thats all, and I am sorry if anyone that has already commented if they are in fact aerial installers, I wouldnt have known.

I know that fitting normal tv aerial is as easy as A.B.C. etc, but when it comes to the issues like I have and am describing then thats when I am bamboozadle, ya know what I mean ?

can you tale a picture of item in attic?

no got ladders now mate

, I did see it though years ago and it had its own source of power etc, it had an actual plug socket next to it and plugged in with power light on, thats when the hooses were literally brand new some years back though, unless any aerial or sat techs that have been out a couple of times since then have touched anything then it will still be the same and no one has been up there recently, not in at least a couple of years.

I could be wrong but it sounds like the main aerial feed from the roof goes into the Sky Box with RF1 into the TV and then RF2 (Magic Eye) feeds back into the loft into some form of distribution box which then feeds both Freeview and Sky Tv from the satellite receiver into all your other rooms.

To test this forget about RF1 and then just connect the main Aerial feed with the RF2 feed with a Female to Female Joint connector and see if you still have freeview in the other rooms

So are you saying that you only get a TV signal when you have the satellite LNB feed connected to either your sky+ box, or VU box (& switched on). If you remove the sat feed from the sky+ box right now, do you lose your terrestrial TV channels?

The sky+ box supplies power to the LNB when in normal standby. Perhaps the VU used to do the same until it went faulty. Although I said earlier it was unlikely, but it sounds like the aerial amplifier is getting it's supply from one of the LNB ports, which is only powered when connected to one of the sat boxes, even though the aerial amplifier appears to have it's own power supply unit. Or there is some kind of relay switch box (?) which connects the aerial feed when LNB voltage is applied.

It would be interesting to see how the cables are arranged in the attic, as it appears that the terrestrial & satellite leads are somehow connected, instead of being completely separate.

LOL, sorry for laughing, that sounds puzzling to me, maybe thats how my explanation sounds even more puzzling, LOL, its like spaghetti junction behind that tv and boxes man,

Yes and no is the answer to that first part of both these questions, if you read on you will see what I mean matey

In answer to the second question though, if I remove the Sat feed from the sky+ box I lose all terristrial tv channels to all tv's yes whether or not the sky+ box is switched on or on standby.
------------------------------------------------------------------------------------------------------------------------------------------

Right, I will try and explain again,

for years now everything has been wired exactly the same as its always been.

There is one Communal static statellite dish with a twin feeds from the dish coming into my house.

There is one terristrial TV aerial with a feed that comes into my house.

All cables come through the attic and then down inside the walls of the house.
(also in the attic there is that self electric powered tv aerial amp multi plug thingy I mentioned).

There are Terrestrial tv wall sockets in the bedrooms and in the living room.

And there are twin Satellite feeds coming from the wall in the living room too.

The Living room TV has Freesat built in which is always where one of the Satellite feeds plugged into.

There is a VU+DUO Satellite box that always had one of the satellite feeds plugged into one Tuner.

and Finally, there is the VERY old Sky+ Amstrad DRX280 Satellite box which has the 3 RF sockets
on it as described earlier and in the photo too.

The Living room TV gets used everyday as usual with its Freesat and single satellite feed, and also
has one of the terrestrial tv aerial feeds plugged into too for use with Freeview when required,
and obviously apart from when the tv is in use it is on standby.

The VU box always sits on standby obviously unless being used/viewed, it has one Satellite feed going
into it as I said.

The Sky+ box sits on standby all the time, it has 3 x RF sockets of which are used.

So we have two terrestrial RF sockets on the Living room wall, 3 RF's on the SKY+ box, an RF input
on the TV, and the other Terrestrial tv sockets are singular in each bedroom.

So, as I explained before, this had all been set up like this the exact same way ever since day one years
n years ago, obviously at the very start when I subscribed to SKY and the sky+ box for a year that was
in use as I didn't have the VU+ box back in the days.

But, I only had a sky subscription for a year and then eventually after a couple/few years I got the VU+
box and then its ever since then the satellite feed has been plugged into the VU box (just using one tuner though as always).

everything always worked fine, didnt matter if the VU box was on standby or switched on, it made no difference at all
to the terristerial tv Freeview tv channels on all TV's in any room.

And then just last week or so I noticed that when the Vu box was on standby there was no signal to the terrestrial tv (freeview) on
both the living room tv and the bedroom tv, BUT if I switched the VU box on then the teresstrial tv freeview channels all came back
on, and its still that way.

So, I thought about the Satellite input on the old SKY+ box and tried plugging in the satellite feed that was in the VU box into the
SKY+ box instead and hey presto, all the terristrial tv channels came back on and the sky+ box is on standby too.

I don't mind doing this just now as my VU box is getting repaired for a weak signal problem within days hopefully fingers crossed,
see here > http://www.digital-kaos.co.uk/forums...eding-replaced

But, I am a bit worried that I get the VU repaired etc and the problem still happens, only thing I would be able to do is leave the VU box switched on
24/7 in that case then, thats all I can think of.

Or, as I think I mentioned earlier, should the communal dish contractors be called out to check things out as I havent done a thing
with the cabling, I still have never ever heard of any TV aerial having anything at all to do with a Satellite feed on a satellite VU
box that doesnt even have TV aerial inputs or outputs on it or nothing, hmmmm
