fact that the manufacturer
also thought about a smart
design for its product. Trans-
mitter, receiver and support-
ing feet all come with a shiny
white surface and create a
low-key yet stylish overall
appearance.
Both the transmitting and
the receiving modules come
with two status LEDs indicat-
ing an established connec-
tion between the modules
and a receiver or TV that is
connected via HDMI.
Our test showed that a
third LED would have been
welcome to light up every
time the system is connected
to the mains and ready to
operate. The reason for this
is that none of the two LEDs
is active unless a connection
between the two modules
has been established and so
you never know whether the
system is turned on at all.
And while we’re at it, a sig-
nal bar indicating the signal
level at the receiving end
would have been very handy
as well.
On a truly bright note, the
manufacturer treated the
reception module to an in-
tegrated infrared receiver
on the front panel, which
means you can use your re-
mote control on the terrace
or in the garden the same
way you would right in front
of the telly in the living room.
So not only does the HDTV

signal from the receiver trav-
el wirelessly to your TV pan-
el, but commands sent from
the remote travel back to the
receiver as well – two-way
communication at its best.
In order for that to work
the Wireless HDMI Extender
converts the infrared signal
from your remote into a digi-
tal signal that is first sent to
the transmitting module and
then transformed back into
an infrared signal which is
finally sent to the receiver
from there. Sounds compli-
cated, but works wonder-
fully.
In the outer left corner of
both modules you can find a
flush mini-switch which can
be used as a sort of range
extender for the wireless sig-
nal (albeit with reduced video
signal quality) and for logi-
cally linking up two or more
modules in the first place in
order to get going.
The back panel of both
modules sports an HDMI port
and a socket for connecting
the external 5V power pack.
In addition, the transmitting
module features a socket for
the external infrared trans-
mitter, while the receiving
end comes with a mini-USB
port.
Antiference ships the sys-
tem with a concise manual
which will tell you everything
you need to know to set up
the system and which comes
with useful illustrations
where required. We were
absolutely impressed by the
build quality of this signal ex-
tender, which met all of our
– admittedly rather high –
demands.
Now that we knew about
any nook and cranny of its
outside appearance it was
time to have a closer look
at the technology behind
the Wireless HDMI Extender
from Antiference.
Transmissions take place
in the 5 GHz range, or be-
tween 5.1 and 5.9 GHz to be
more precise. We find that’s
a smart choice by the man-
ufacturer, since the overly
popular 2.4 GHz range has
become a bit crowded with
all the countless WiFi rout-
ers, analog transmitters, mi-
crowaves and other devices
in recent years.
