So I got a new to me 2023 mack granite tri axle dump….switched my cobra 29 chrome over to it hooked everything up and went through the calibration stuff… my SWR on the swr setting is around 1.5…if i flip the switch up to s/rf and key the mic the meter spikes up high but the ANT light doesnt come on….is this normal or will i damage my radio? Pretty new to CB so sorry if its a dumb question
