It most likely means that unwanted RF from your antenna system is getting into your transceiver's audio input (microphone), distorting your audio. Some solutions are reducing any common-mode RF on your feedline, moving the radio and antenna further apart, or using ferrite and/or capacitors on the audio line.

RF Appears on the two signal lines simultaneously in the same direction and phase A common-mode choke, produces equal and opposite magnetic fields that cancel one another. A capacitor from each line to ground can also be used. Differential-mode appears on two lines of a closed loop – (car battery to mobile radio)

This can cause all sorts of problems, such as RFI (radio frequency interference) and can even cause the rig itself to misbehave. I’ve worked hard in my shack to keep the RF away and have been mostly successful, although on 80 meters I have to shut off the computer speakers because they buzz loudly.
