Default Dual tuners loose signal

My HTPC came with dual digital TV tuners (two cards).
It works fine with just one connected but if I split the leads to
connect both with a normal splitter I lose most of the stations.

I had a new antenna fitted when I switched to freeview about five
years ago. I worked fine with the Freeview box 'most of the time' -
in 'bad' weather I do sometimes get freeze frames or pixilation.

So the signal is marginal and your resistive splitter is probaly
halving what is available.
I suggest you ask in:-
uk.tech.digital-tv
But before you do - you will need to say which town you are in and
which transmitter you use. I would also suggest stating if you had
new aerial coax fitted and what type of aerial (18 element?
wideband?) and its location on your house/flat.
My guess is that amplification will not be a real cure unless
(possibly) on the mast.


Thanks for that.
After doing a bit of checking I decided that as you say the antenna would
probably need changing and I would also need new cable as that was not done
the last time.
Due to the cost of that option I though it worth the risk of wasting £20 on
a 4 db two way amp and some 75 ohm terminators on the unused sockets .
And it worked! I have all the TV and radio stations with the two that I had
with the single tuner.

Though I suspect in the long run I will need to re-cable as the stuff in the
walls and to the antenna must be at least twenty years old.
