@Kevin_Z  Thanks but no it doesnt really help.

I was looking for a way to view the signal strength details for each of the 2 antennas seperately so I could identify which antenna had a problem, such as by accessing a hidden menu or telnet /ssh.

I eventually found a bad connection to the feed cable inside the external antenna case.

@Techcareuk I don't think there is anything stopping you removing one antenna and then viewing the signal strength for the remaining antenna.  Then repeat for the other antenna?  that might work?
