ski dish coax question

im about to move into a new build property and managed to get sky to agree
to installing a free dish.There is a standard tv point and with coax runing
into the loft. When the engineer comes to install the new dish ,will he
connect to this or will he try to run a cable down the outside of the house
and drill through the wall? also,I want to put my own tv point in the main
bedroom, so if I use a 'T' connection in the excisting coax that will run to
the dish, can I use a ski eye infa red so I can view ski in the bedroom?

Not quite correct! The LNB (the B is "block down-downconverter") downconverts
the microwave signals (~10-12GHz) (which would need waveguides) to ~1-1.5GHz
to pass down the coax. Higher than normal UHF frequencies (so better coax
needed) but still not microwave!
