Default DAB antenna

Hello

Can anyone advise please. I have a new DAB tuner which works fine except
the
digital signal is not very strong around here. I am getting some 'popping'
sounds as a result. The Bit Error Rate is about 0.04, less than the
critical
0.05, but not brilliant. The indoor ariel supplied is 6 inches long. I
have
tried moving the indoor aerial around within the range of its cable with
no
real improvement.

Is there anyway of improving reception without installing an external
aerial?

Thanks

You could try sticking a bit of aluminium (aluminum) foil to the card from a
cereal packet. Fold the cardboard to form a right angle and stand it with
the folded edge vertical near to the antenna to form a reflector. Adjust for
best signal strength. For a 6 inch antenna, the card only needs to be the
size of an A4 sheet of paper, around 8 inches by 12 inches. Fold in half so
that you have two surfaces at 90 degrees to each other, 8 inches by 6
inches.

If this doesn't work, you need a bigger antenna.
