The maximum radio range that can be achieved with this device strongly depends on the conditions of
the individual application.
The following general rule applies: The higher the antenna is positioned the better the reception is.
The alignment of the antenna is important, too. Due to the fact that the transmitter antenna is mounted
vertically the receiver's antenna should be aligned vertically as well. Furthermore it should protrude
without being covered by the housing.
The radio signals should not be shielded by any conductive material, e.g. cables, around the antenna.
A radio range of 500 m is possible with this device outdoors if conditions are good.
The actual conditions in practical installations may be different than the ideal ones, resulting in lower
range. Especially a missing free line of sight or obstacles like reinforced concrete walls lead to a
considerably reduced radio range.
By performing a radio range test you get a result as a percentage value and if necessary you can take
rather simple measures to improve the reception considerably.
The radio range that can be achieved depending on the conditions is:
Outdoors: 150 ... 500 m
Indoors: 50 ... 200 m, in large venues and with free line of sight also much more
13. Radio range test
As soon as the device is in receiving mode you may invoke a radio range test any time.
Make sure that all conditions are similar to the situation when the device will be used later when firing
and start the test at your controller.
If the device received the test command the green LED 'Range Test' will be on. That is the indicator
with the antenna symbol next to it. The result is being displayed on the LED bar simultaneously.
As a rule of thumb the following applies:
= approx. 90% of the maximum field strength
= approx. 70% of the maximum field strength
= approx. 50% of the maximum field strength
= approx. 30% of the maximum field strength
= approx. 10% of the maximum field strength
A result of two LEDs (i.e. 30%) is sufficient for a good radio contact.
The displayed result can also be understood as remaining radio range. That means if you see three
LEDs (i.e. 50%) you can approx. double the distance until the signal becomes too weak for reception.
