And frequency band - if you try to get the high band on one tuner and the 
low band on another it'll fail.

Also, your splitter needs to block the power feed and tone signals from 
one of the tuners or you're likely to start blowing stuff up.

I grabbed a quad-LNB off ebay for about 8 quid - does the trick perfectly.
