But in addition to this, I also (with out any other ariel in) get BBC1, 2, ITV, C4, C5 RF channels as well, on their standard broadcast freqs. Coincedenly the RF also shows a poor Sky Sports 2 Picture, even though we don't have that channel.
Now I don't know which RF Freq the DTT channels get broadcast at, but I was wondering if the STB would also output that....

The STB does not output the "other" channels it simply passes them through and mixes in the decoded digital channel.
The "other" channels will either come from a standard ariel (in the case of newer boxes) on their broadcast frequencies or from the cable itself on different frequences. In the case of newer boxes the DTT channels will also be passed through the STB.
The reason that the DTT channels are not also broadcast down the cable is that the bandwidth is reserved for the digital cable channels.
