Figure 21: Mandatory metal free space around RF antenna inside the DFGT

The crossing of the arrows in Figure 19 indicates the position of the RF-antenna inside the DFGT.

Figure 20 gives two examples of the influence of the position of the free path in relation with the signal strength. In

both examples, the DFGT is positioned in such a way that the preferred direction of the RF signal is to the front of

the Decorative Fire. However, in example A there is a free path for the RF signal (no metal) to the front of the

Decorative Fire. In example B the free path is located at the side of the Decorative Fire. The differences in the

signal strength (RSSI) outside the Decorative Fire are evident. The level at the front of the decorative fire is very

good (-40) in example A, but much too low (-90) in example B.
