Reference Tuner-1.0
AERIAL REQUIREMENTS
The tuner aerial should be mounted on the roof, clear of obstructions and also as high as possible. Horizontally
polarised aerials will respond to almost all commercial broadcasts whilst partially rejecting police and taxi
transmissions, and are therefore recommended. Use of an aerial preamplifier will disturb the muting operation of
the tuner and may cause cross modulation problems. Such preamplifiers should only be used as a last resort.
In most commercial radio broadcasts are usually radiated from different sites even though the target areas of the
services may be similar. This means that unless the transmitters are in almost the same direction looking from
your house, an aerial aligned on one transmitter will give less than optimum performance on the other. In these
circumstances you should fit an aerial rotator, or a less directional aerial if appropriate. The more sensitive and
directional the aerial you use, the less good will be the reception in directions other than the one towards which
the aerial is pointing. If you are particularly interested in receiving a wide range of VHF transmissions an aerial
rotator is a necessity. Your dealer will be familiar with local conditions and will be able to advise you on which
stations are capable of being received satisfactorily.
CONNETIONS
The FM aerial input socket could be connected via 75ohm low-loss coaxial cable to a suitable roof-mounted
directional aerial. The tuner’s audio output is set to 700mV at 100% modulation and should match almost any
preamplifier without difficulty.
