[Amps] High SWR

VSWR in broadcasting applications is especially a concern when complex 
modulation schemes are used.  FM stereophonic separation is highly dependent 
on line VSWR.  Line reflections degrade stereo performance.  In NTSC 
television transmissions, line VSWR causes "ghosting."  Even modest amounts 
of VSWR can degrade audio and video performance.

As broadcast operations turn more toward digital modulation schemes, VSWR is 
still important for proper decoding albeit some modulation schemes are more 
or less susceptible than others.
