4. PENETRATION ANGLE
The angle at which the transmitted signal hits the wall is very
important. The effective wall thickness – and with it the signal
attenuation – varies according to this angle. Signals should be
transmitted as directly as possible through the wall. Wall niches
should be avoided.

Avoid an unfavourable penetration angle by repositioning the
Transmitter and / or Receiver, or by using a Repeater.
Do not position a Switch Receiver behind a Transmitter. In this
position the signal strength is greatly reduced, even if there is no
wall in-between.
5. ANTENNA INSTALLATION
Switch Receivers should not be installed on the same wall as the
Transmitter. When positioned near a wall, the radio waves are
likely to be subject to interfering dispersions or reflections.

In a similar manner to the comment in the previous section,
positioning transmitters and receivers along the same wall will
mean the signal strength is greatly reduced.
6. DISTANCE BETWEEN SWITCH RECEIVERS AND A SOURCE OF
INTERFERENCE
The distance between Switch Receivers and other transmitters
(e.g. GSM / DECT / wireless LAN) or high-frequency sources of
interference (computers, audio and video equipment) should be at
least 500mm. However, Echo
™
Transmitters can be installed next
to any other high-frequency transmitter without a problem.

7. USE OF REPEATERS
In the case of poor reception, it may be helpful to use the repeater
functionality built into switch receivers or a dedicated Repeater.
The 10AX Switch Receiver/Repeater (K5420R) is also a repeater
when not programmed with any switches. The various possibilities
of use are shown by the illustrations in sections 3. SCREENING
and 4. PENETRATION ANGLE.
A Repeater has similar requirements in being positioned as a
Switch Receiver, i.e. it too has an antenna and needs to receive
the signal from the Transmitter and be within range of the Switch
Receiver with which it is intended to communicate.
While planning, it may be worth considering retrofitting the system
with a Repeater.
