How do i connect 2 tvs to one set top box, but 2nd tv is 30m away. ?

for first tv near settop box, use scart. for second tv use a normal aerial extension lead, it will plug into the back of your box, and the socket it plugs into will look like the the one where the aerial would plug into, probably says signal out etc. then just put this lead into the back of the other tv where the aerial would go, then simply tune your tv into the box, this will probably be the hardest bit, but just tune it in like you would a new channel. because it is 30m away you might want to use a signal booster which doesnt cost too much, though i used a 30m extension lead before with no booster and i had perfect signal, or you could use signal booster/splitter and just tune both tvs in using two extension leads. this way you put signal out lead into booster and have two leads coming out,one to each tv

I think you need to buy one of these with your cable.

extention lead

Good luck

30m of cable.
