William : I had also meant to say that with regards to your magic eye I presume that you have switched the power on for the RF2 out via the installers menu?
If you have then connect the magic eye directly into he Sky boxes RF2 to make sure that it is working OK, if it is but not in the bedroom then that indicates that you have either a short circuit on the link cable between the two positions or that you have a Non-DC pass splitter installed on the coax, and this would require changing to an alternative type that does have DC by-pass.

Can you explain carefully where the piece of wire needs place between is it the "bare end" into "aerial IN" in the back of sky box and the "un-stripped end" into the end of my co-ax end which is still plugged into my main aerial point on the wall plate marked " TV "

If my aerial signal providing freeview is overly strong therefore "swamping" the satellites signal would fitting an attenuator maybe solve the problem

Why is there two Al Jazeera channels on two separate EPG numbers? Both broadcast on COM6 so can't they timeshare on the same EPG number?
Al Jazeera Eng is on air 1800-2300 on ch.83 and Al Jazeera 6-8 is on air 0600-0800 on ch.84. Surely they could timeshare on the one channel number to save being on two different channel numbers at different times of the day?

William : No! as the reason I suggested trying this is because that going by what you have reported it appears to be the case that when an "electrical" connection is made between the main aerial and the outer casings of the "F" connectors (in effect all metalwork) that this is whats cutting the signal out.
The approximate post code that you provided was suffice to verify that your Sky boxes modulator was not being swamped by a Freeview signal on the same channel and so that possibility can be left out of the equation.
Regarding the wire referred to, the whole purpose of this is to "induction" couple your main aerial system into the Sky boxes normal aerial input so that the signal could transfer into the Sky box without an actual electrical connection being made between both, as this in theory should allow the Freeview signal to transfer without the electrical component linking both which should stop the Sky signal from cutting out.
The wire having a proper connection into the Sky boxes aerial socket is just done for convenience, and the un-stripped end is to ensure that an electrical connection is "not" made between the wire in the Sky boxes aerial socket and the lead that goes to the wall plate, as signal transfer does not necessarily require a positive (wire to wire) connection to be made.
If you were an enthusiast in this field I would normally have suggested that you use two small capacitors (100pf each) to link the boxes braiding to the normal aerials same, and do likewise with the inners of both coax's, as this method gives a stronger signal.
Induction transfer was the reason for your TV receiving Freeview whilst the cable was on the floor not connected to anything.

I can see some 100pf capacitors on eBay fairly cheap but they are ranging from 50V to 15KV any particular ones and when I get them shall I just hold them in place between the 2 points of contact ( braidings and inners )

William: Simply imagine that you have a piece of coax that you have just chopped in two and you want to join it up again, the only difference being that instead of joining the inner to the inner you do it through one capacitor (inners of each cable joined via the capacitor) and with exactly the same thing being done with the braidings.
This of course should not be necessary and will only "in theory" stop your Sky signal from cutting off, as I suspect that there might be a potential difference between the outer of the coax plug and the "F" connectors same, although only a voltmeter would reveal that.

William: Set it on a 250 volt or slightly more AC range and check if anything reads between the outer of the coax plug and the side of the "F" connectors, the latter connected into the Sky box but the coax connector "not". (free standing)
Should nothing be indicated then try it with the meter set on DC, giving an update on results, and now I am aware you have a meter get someone to view the remote TV position to check if the signal cuts out when you have the meter across these two points.
Another thing that I should have suggested a few postings ago was to temporarily position the remote TV near to the Sky box and connect it into the boxes RF1 socket with a jumper lead, then see if it still cuts out when you connect the main aerial into the box, as I want to eliminate any possibility of a problem existing with your wiring.
