consisting of voltage and current. When
the antenna is the proper length the sine wave begins at one end of
the antenna and ends at the other end of the antenna.
antenna is not the proper length, too short or too long, the sine
wave doesn't match the antenna length, causing standing waves, or
High SWR could result in no radiated energy.
also causes RF feed back, radio energy backing up making components,
mikes, key, etc., hot to the touch. SWR reading should be less than
1.5 to 1, but SWR reading up to 3 to 1 will work.
