Another problem if the Q gets too low is that the harmonic output tends to start rising. If Q gets extremely low, there can be enoguh harmonic that the apparent SWR rises, since the antenna isn't matched at the harmonic and so the SWR meter sees reflected energy at that frequency. I once saw it happen in a bodged installation where they tried to pull the tx a long way LF outisde its real frequency range.
