What is worth mentioning,
both outputs of the Twin LNB
and all four outputs of the
Quad LNB were almost iden-
tical. So none of the outputs
was weaker or stronger than
the others with the same
Then we measured and
processed the MER results.
And here we had another
picture. We may say that
the MX-16 matched our ref-
erence, the MX-KT22C was
somewhat worse and the
MX-KQ24C was again almost
equal to the reference.
The reason for this is
clear: the MX-KT22C has
been designed as a high
output LNB and due to that
its noise performance is not
as good as the normal out-
put level companions (Single
and Quad in this case), whch
is due to increased inter-
modulation in such high gain
LNB. However, this makes
this LNB a favorite for re-
ceiving strong satellites
connected to a distribution
system with significant sig-
nal loss due to long cables
or many switches.
The MX-16 and MX-KQ24C
did not have such a strong
output signal but performed
very well in signal qual-
ity measurements. We can
recommend them even for
difficult reception condi-
tions. They they perform as
well as the best LNBs on the
Finally, we measured cur-
rent consumption of all
LNBs. Here are the results:
MX-16—72 mA
MX-KT22C—104 mA
MX-KQ24C—152 mA.
The d.c. currents are quite
reasonable and similar to
other devices of this kind.
They will not cause any
problem for any receiver or
