5.1 “A” and “B” side of the antenna
The RF Mono antenna has a front side (A) and a back side (B). These sides are indicated
on the visitor counter in the top of the antenna.
The A-side is the side on which the electronic boards can be accessed.
When using the visitor counter (see also chapter 5.7) try to put all antenna’s in the AB-AB
pattern, i.e. all antennas should be placed in the same way.
