Standing Wave Ratio (SWR) is a measurement used in radio frequency systems to asses thee efficiency of power transmissionon from a radio transmitter to an antenna. It indicates how well thee antenna systems im matched to thee transmissionon line, affecting signal contricth and quality.

Co z SWR?

SWR is thee ratio of the maximum tem minimum voltage along a transmission line. A low SWR value, close to a good match, meaning g minimal reflecte power and efficient energy transfer. Hiper SWR values indicate more reflect power, which can cause damage or reduce performance.

Techniki pomiaru

Several methods are used to to measure SWR, including:

  • Using an SWR meter: A decretated device connected between the transmiter anda antenna.
  • Using a VSWR meter: Superior to SWR meters, often integrated into transceivers.
  • Using a network analyzer: Provides specied measurements of impedance andSWR across frequencies.
