Splitters are very cheap items -- I suggest you get one and try it.
Got a tip for us?

Then more likely than not your signal strength is not good enough. Are you using a correctly positioned roof aerial?
i got a good question for someone to answer
i have a aerial in my loft, running down to a tv and the eyetv, the tv can pick up EVERY freeview channel perfectly, but the eyetv cannot receive certain channels like channel 4 and itv, but receives others like bbc fine
what.the.hell?

I'm surprised that in seven pages no-one has mentioned that the six DTT multiplexes (in the UK) are not equal. Also, within one multiplex, the bit rate for "channels" can differ- as can the picture resolution.
Importantly, the actual transmitted power varies- hereabouts, the BBC Muxes are 10kW while the ITV/C4 Mux is (I think) 6kW.
However, most importantly, the ITV/C4 Mux is encoded using 64 QAM in an attempt to cram four times as much info into the channel, c.f. 16QAM for BBC.
So ITV/C4 is difficult to receive at adequate s/n, (as is C5 but because it is usually transmitted at low power). Your IDTV (or STB) is doing a better job with a marginal signal than the DTT adaptor at your location!
P.S. Believe it or not, the mini magnetic aerial is intended for mobile reception- cars being steel while furniture is not in general. The signal strength to achieve this (at up to 100 km/h) is available in major conurbations in Germany. It has been trialled in the UK.
I'm not surprised that nobody else has mentioned muxes and QAMs and diddleydoodahs in the preceding seven pages, since we are all supposed to post in English for better communication.
I'm sure you posted a lot of interesting information. If only we could make head or tail of it.

on the multiplex c4 is on, the signal strength on the tv is about 70 with a bit error level of 0
bbc channels are 90 with error level of 0
whereas on my eye tv signal quality is 100% and signal strength is 42 for bbc channels, and on channel 4 the signal strength is 43.5 (higher) and signal quality is 0
i just can't understand why it drops so low when the signal strength is higher
i used to have all channels working which makes it that bit more frustrating, could it have happened when i upgraded the eyetv software?

I recently moved home and went from having all the channels to about half a dozen using a proper rooftop aerial. Just recently I upgraded the EyeTV software to version 2.5.1 (I think I was using 2.4.1 previously), re-scanned the frequencies and this time round it picked up everything so maybe that would help.
The problem here is that the "signal strength" on a DTT receiver is not the power being received as it would be on an FM tuner, but a "figure of merit" calculated from recent digital data. I suspect different manufacturers use different algorithms. Signal quality refers to the error rates (presumably failed checksums). Clearly the ITV/C4 Mux is right on the edge of usability.
The reception of DTT signals can depend on tiny changes in orientation of your aerial- I'm afraid you need to climb into the loft if you must use the downfeed from that aerial. I've had success with amplified set-top aerials, allowing portability.
eye tv dtt stick cannot pick up most of channel 4 and itv channels
well my eye tv stick is connected via cables directly to a roof top aerial. to date i can pick up most channels apart from the channel 4 and itv ones. strangely i can get itv 2 + 1 and E4 + 1.
when i first installed the software and connected up some 3 months ago, i got all the channels no problem. i have done nothing different apart from updating the software but this was some time after i lost channel 4 and the itv programs.
im baffled. anyone got any ideas, im thinking maybe my aerial has moved slightly but if that was the case i would not get itv 2 + 1 and E4 + 1

This is because itv2+1 and E4+1 are transmitted on different multiplexes (Mux D and MuxC resp.) from itv1 and C4 (Mux2). Different multiplexes are on different UHF channels so your situation is analogous to someone who can get the all four main analogue channels but not, say, Channel 5.
Three months ago your reception of the ITV/C4 Mux was probably at the limit of usability and has now fallen off the "digital cliff". This could be owing to a small change in aerial direction or water in the downlead or even a tree with more foliage in the way.
Note also that Mux 2 is 64QAM c.f. 16QAM for MuxesC&D and is consequently more vulnerable to small changes.
thanks dark fiber for reply
well managed to sort it out, by complete accident all i did was close down the eye tv software, pulled all leads out - thats the usb connection and the coaxial lead thats connected to the wall socket which leads to the roof aerial. simple put them together again and opened eye tv. To our astonishment itv and channel 4 were back. sometimes we lose it again its been twice in 2 weeks when that happens we just pull leads out and put together again and the channels are back.
thought i mention this as it may help others with same problem.
regards to dark fiber the information was helpful its good to know.

Glad to hear you're now enjoying life at the very edge of the digital cliff!
You shouldn't have to go through this palaver, of course- have you tried disconnecting and reconnecting the aerial only? What happens to the signal strength indication?
I use the aerial which came with my Miglia TV mini. It's a tiny black thing, but in a stroke of genius it has a magnet on the bottom. I've attached the aerial to my radiator in my bedroom with the magnet and this results in the whole thing becoming like a giant metal antenna. Works great.
I recently had the same problem. I used to have channel 4/itv etc. and about 4 weeks ago they disappeared. Now I am wondering if there is another hardware/product which uses a different technology which hasn't got the same problem. Maybe even offered by Elgato?
The "problem" is intrinsic to DTT (DVB-T) in the UK, at least until the "digital switchover" occurs in your region. Then digital signals will be broadcast at significantly greater power. In the short term, the cure is simply a better aerial
