Hi all Many thanks for taking time to read this. I have done a multi room install in an over sized property. 1 Aerial cable from all tv points 10 total all cables to central point in loft where I have installed a booster Prostar http://cpc.farnell.com/proception/prostr10s/star-box-home-hub-10-way/dp/AP01853 Customer has had sky installed in downstairs room. 2 cables direct from Sky dish to receiver. I have installed digital aerial which cable goes down directly to Sky hd receiver. RF out on hd box switched on and to channel 68 RF out goes up to loft aprox 20M to Home hub, From there distributes to all other rooms. Freview Digital tv has excellent reception throughout property but the RF out for sky use is very poor and using the magic eye most rooms the led does not even light up So cant change the sky channels. I have checked all F plugs at booster for stray strands. Please does anyone have any ideas which would be greatly appreciated.
