To obtain the best
performance
of
whích this
unit
is

the cable used to connect
this unit
with the
special

for FM reception should
be
75O coaxial
cable
(type
RG-59/U

which res¡sts
the
effects of external noise.
3) lmpedance
matching
lf
it ¡s
impossible
to make a d¡rect connection with
75O
coax¡al cable
from
