[Discuss-gnuradio] RFX400 Antenna Connection

[Jeremy Chew]

Hi,

I am trying to eliminate channel error by using a cable to connect two 
RFX400s together. The strange thing is that nothing useful seems to get 
through when the radios are connected by cable. I have tried attenuation in 
the range from 0 to 40dB and with several cables to no avail. Using antennas 
works much better.

Do you know what is wrong? And what should the cable attenuation be?

Thanks,
Jeremy
