FiPY Sigfox range reception

[mwindley]

I have been disappointed with the reception results of my FiPY, using Pycom SIGFOX example code, std whip antenna here in Adelaide Australia.

Can i be assured that FiPY is Class 0, 22 dB device for Sigfox?
I found no possibility to a requirement to set a parameter such as TX_Power or similar to achieve 22dB
Will it just function at this level given i am region 4 for Sigfox over here.

Should i go to a better antenna as only next option, 13bD yagi for 920 MHz.

Works well to a range of half described in Sigfox coverage map.

Thanks in advance for any advice or experience.
