868.4 MHz (Europe) or 915 MHz (America, Australia, Canada and
New Zealand)
In the 915 MHz frequency band (912.6 MHz to 917.4 MHz), one of 10
fixed frequencies can be set.
300 m at 868.4 MHz or 200 m at 915 MHz
Range when using the antenna holder for wall mounting with a 3 m
antenna cable; when mounting the antenna directly to the receiver, a
reduction in the range must be taken into account.
> -90 (with stationary transmitter)
The RSSI value is an indicator of the strength of the received signal
(theoretical value range: -120 to 0).
