Average power is nearly constant, but for every value of SWR 1:1, peak
power along the line is not. I have seen many examples in FM broadcast
stations where their transmission line was damaged at intervals of 1/2
wavelength due to a high mismatch at the antenna, or a precipitating
failure in the line itself.


Current maximum points are prone to overheating. Voltage maximum
points are prone to arcing.
