Connecting the FM tuner
The 504 Stereo FM Tuner is a very sophisticated unit, which will
deliver superb quality sound. However, unless the signal
delivered to the antenna socket of the 504 is of sufficient
strength and quality, you will not enjoy the maximum benefits of
your new tuner. We cannot emphasise enough the importance
of a good VHF antenna and downlead.
However, as reception conditions vary so much, it is impossible
to give more than broad advice, and we recommend, therefore,
that you consult your dealer or antenna supplier who will be
familiar with local conditions and will be able to advise you on
the right equipment for your installation.

To connect an antenna
A suitable VHF antenna or VHF cable signal must be connected
to the socket marked ‘RF input’ on the back of the tuner. You
are advised to use a high-quality, low-loss coaxial cable. Cables
which have a solid screen will give superior performance.
Please note that the antenna must be intended for unbalanced
(ie coaxial) connection. Antennas intended for, or connected
with ribbon cable are unsuitable. If your antenna uses a ribbon
cable then ask your dealer for a ‘balun’, or have it reconnected.
Ribbon cables are not acceptable proof against RF interference.
