Marcus is right, but: Also, what is to be clarified? 20 dBm (or 10 dBm) is way more than 0dBm, true, but when would you ever expect a receive antenna to generate 1V, if you're not standing right next to a massive broadcast transmitter, or radar transmitter, or put your WiFi antenna in a microwave oven?
Aside from that, 1 kHz is way below the lowest frequency the B2xx can receive (not that frequency matters at all for the power aspects in general, but that 1kHz wouldn't even pass through the coupling capacitors without significant attenuation. 1kHz is, for all practical issues of RF communications, DC). Also note that 0dBm is not the maximum sensibly receivable signal; your receiver will be clipping at this point very much! Sensible receive powers are more in the range of -20dBm or less.
