Just was wondering why I lose Satellite signal when I unplug outside aerial?
Can have aerial plugged into vcr with vcr plugged into nothing else and I have sat signal. As soon as unplug aerial lose sky signal.
For some reason it needs sat cable as well as the outside aerial connected to something.

Why are you viewing via the RF feed, this is the lowest of connection methods. The RF feed is at the bottom of the heap, from RF you go to composite, then S-Video then RGB or YUV(Component). If you have spent all the money on a MySky you should be using a better interconnect than RF.

Other than that you will probably use the RF feed to run other TV's in the house. There is no dependancy on having an RF signal going into the MySky to get a signal out. There is some unique fault in your setup, or something odd in the way you have connected. it.

I am not. I am viewing with composite. Just if I unplug the outside aerial I get the rain fade message. The outside aerial can be plugged into something that is not connected to my tv or mysky and then I get signal - ie there is no connection in anyway to the mysky box from outside aerial.

Thanks for answer, it looks like the sky installer did something funny when setting it up, as I wouldn't have a clue how it's wired under floor.

If mysky loses signal second decoder does as well. Can unplug outside aerial where second decoder is and all fine, also second decoder goes down has no effect on mysky.

Are you sure you're not unplugging the RG6 sat connection?

It's just the socket in the wall that aerial for a tv, vcr etc goes to.

The satellite cables come out of sky box to splitter, then single white cable from there goes through wall and under floor. I'm not touching those.  I'm guessing by RG6 those are what you're referring to.

So lets get this right, the cable going to your antenna, if not connected to an RF input either on the MySky or TV or VCR, then you get no signal on the satellite input.

Is there an antenna amplifier somewhere?

Is sounds to me like if there was an amplifier in the antenna feed that when not connected to anything it breaks into oscillation at a frequency that intereferes wiht the Lband IF . If there is no amplifier on the antenna feed then it would be very odd that a totally passive antenna system could cause such an effect.

The behavour you desribe is not normal

That's right. Oh well it's all working that's the main thing. Next time I have a sky installer out I'll ask them about it - all going well it'll be when Hi Definition comes out and if the prices for it are ok.

Thanks.
