DAB Aerial Saga-the conclusion

I now have a DAB external dipole aerial installed and the system is
working perfectly!

The problem appeared to be quite contrary to what I thought and
something no one else has suggested during our exchanges,, that is the
signal being received was too big.  The received signal by the dipole
was 98db whereas, as I understand it, the signal should not exceed
70db.  The aerial fitter installed a 20db attenuator and everything
then fell into place.

We tested with and without the attenuator.  Without the attenuator the
set did not respond whereas with the attenuator the signal at the set
was 68db and everything was perfect.

The fitters said they had never experienced this 'problem' before,
that is the signal being so large as to 'swamp' the receiver.  I guess
that explains why the internal aerial 'worked' whereas the external
aerial (without attenuator didn't).  The walls and other impediments
to the signal to the internal aerial reduced signal strength to within
the required band.

As a matter of interest the time taken from ringing the doorbell until
the guys left the premises, cheque in hand, was 50 minutes.

As for price, £90.00.  I guess from previous exchanges on this subject
they must be 'cowboys' :-)!
