Radio connectivity
A good radio connectivity is an essential part of having a good performance when using wireless
ignition systems. Taking note of a few simple hints can drastically increase the connectivity between
Transmitter and Receiver.
6.1.1
Overview of Radio wave propagation:
Radio waves are electromagnetic waves, flowing with near light speed (~300.000km/s) .
Radio waves frow freely in the vacuum, or air, but can be reflected by metals, or absorbed by natural
materials like water or wood.
6.1.2
Positioning your devices:
If possible, position the transmitter and receiver in a way, that no objects stand between them.
Avoid objects made of metal especially (eg.: Steelconcrete buildings, metal fences, Tanks, Ships,...) as
well as mountains.
Theoretically, it is possible for a receiver to receive a signal behind such objects, since radiowaves
break or reflect on objects, and thusly an indirect contact can be made, however the full range can
only be used by a direct line.
Under no circumstance should Transmitter or receiver be covered by metals, since this materials
could shield them from radio waves.
Ideally, all devices should be on a heightened position. (eg. Transmitter on a table)
Because of the radiance, all antennas shoudl stand up straight (vertical). If possible we recommend
using magnetic antennas.

Safety hints:
The system may only be used for the ignition of pyrotechnical effect, and may only be used by
learned pyrotechnicians. The general rules for the usage of pyrotechnical items are always to follow.
After switching on the device (even in testmode) no persons may linger in the dangerous vicinity of
the effects connected to the devices. Workings at the devices or firing ramps may only be done if the
devices are switched off. During the show, the safety distance to all connected pyrotechnical effects
must be kept. Working on the system during the show is not allowed.
During the setup of the System and the firing ramps, it is recommended to ensure the devices can't
be switched on (taking the key with you). Under no circumstances may a transmitter be left alone
without supervision, except when it is proofed against being switched on by others.
