Very simple installation
Strong and very well regulated output power
Perfectly clean output spectrum
Fast channel zapping
Very low terrestrial tap loss
Hardly noticeable small degradation in noise performance for
very high symbol rate transponders (30 Ms/sec)
cal oscillator in the SCR has
to tune to another frequen-
cy. But at the same time this
means the local oscillator in
the tuner of your receiver
does not have to change fre-
quency at all, as it is fixed
to receive 1076 MHz or 1178
MHz for all the time. As it
turned out, in our test chan-
nel zapping was even faster
when we used the SUS 21 F
than zapping without it. We
did not measure it because
the difference was a split
second but we trust our im-
pression. The local oscilla-
tor of SUS 21 F was tuning
faster then the local oscilla-
tor in our receiver. A tip to
our chouch potatoes: if you
want to speed up your zap-
ping speed consider using
the SUS 21 F as a way to by-
pass frequency changes of
the internal oscillator of your
receiver.
Finally, we also checked
the terrestrial signal routing
(FM, DVB-T, CATV). Signal
from a terrestrial antenna
can be combined with one
of the two satellite signals
entering SUS 21 F and then
be passed through the same
single cable and feed the an-
tenna input of your TV-set.
SPAUN promises only a 2 dB
tap loss for the terrestrial
signal. We measured the loss
at 634 and 666 MHz and it
was even better: just 1 dB.
And by the way: the recep-
tion of the terrestrial signal
is also possible when the
satellite tuners are switched
off.
We had fun experimenting
with the SPAUN SUS 21 F. It
didn‘t affect performance at
all and even improved chan-
nel zapping. A clever way to
feed twin receiver with PVR
without having to install a
second cable.
