In the loft there is a cable to the light. Cable is near amp.

So is it not likely that the amp/aerial are too strong.

The white sparks on analogue are rare and usually on start up of any channel, seem to go after about 2 mins.

Tonight watched 2 hours of digibox TV and had two split second freezes it is definatley better now the aerial is on the roof.

I just want them to say why what is happening is happening. I presume if left it wont short/damage anything, because if it is my own electrical interferance that is OK compared to being ripped off, but how do you trust the people who put it in the loft!!!?

So you think aerial height going up 2 or 3 foot wouldn't help?

Additionally he did show me the digital read out in the loft, bedroom and lounge and the 4 signal lines he told me he uses to decide if digital signal OK were above the 50% line constantly, he could not explain freezes every 10 mins.

Now things have improved with outside aerial, what does that mean it could be as the amp hasn't moved, the aerial has. Less freezing, but still once or twice an hour whatever channel I'm on now, yet all digi signal stregnths are 100% they were 50-75 from loft.

I'm beginning to think I'll be stuck with this and hope it improves when digital switchover happens or will that not help my problems?

SO AM I LEFT WITH :-

Internal interferance

Poor cables installed by builder x two

Too strong signal due to amp -(what annuator should I try 6db, 3db?)

Aerial too low as it is at roof line, could go up 2 or 3 foot to be as high as others on estate

Is the above the only likely causes now?

THANKS FOR ALL ADVICE, I can't believe a week of aerial install has turned into such a hassle!!!
