Hi

I've just moved into a rented property. it already has a dish installed and all the wiring already seems to be done. i have never used sky before but i bought a sky box off ebay cos i wanted to view the free sky channels. i connected the sky box to the co-axil cable connected to the dish but when i turn the box on it says no signal is being received. could the dish be facing the wrong way? or is it a dish for something else (eg some other satelite tv). the dish is round where as the sky dishes i have seen in the past are more oval in shape. would a rounded dish not work with sky and would any lnb work for sky or is it a specific lnb for sky

how do i rescan the satellites
