BTW, it's important to know that for a 4W CB having an impedance discontinuity is irritating and may damage your radio but when you put 50, 100 or 1,500 watts down the feedline an impedance issue increasingly becomes a major problem. A spike in impedance means that energy gets converted to heat quicker and you melt coax or worse.
