Lothar, What is this? -What cable to use is a common question that is asked so often I decided to come up with a semi-stock answer.

This table shows the typical cable lengths you should never exceed for RX / RO only use at various frequencies, generally at the -3dB loss point, but shorter cables are better of course. Think of it as a max length assuming you have and SDR with an amplified RF front end that is before any SAW filter for a narrow signal like 1090 MHz. Take 2/3rds of the footages shown for 2 dB loss for example at any frequency. As we used to say in my commercial days What’s 2 dB among friends?
