Antenna system matching can be analyzed by determining the Standing Wave Ratio (SWR). Which of the following is the best test procedure to measure the SWR of a marine VHF antenna system?
A
Insert an in-line RF Power meter between the VHF radio and an artificial antenna, set the radio to any channel, key the microphone, and read the measured value.
B
Insert a SWR meter between the VHF transmitter and the coaxial transmission line connected to the antenna, set the radio to channel 16, and conduct a "RADIO CHECK" with a nearby U.S. Coast Guard station or vessel.
C
Insert an in-line RF Power meter between the VHF radio and the coaxial transmission line disconnected from the antenna, activate the Push-To-Talk (PTT) circuit, and read the forward and reflected values.
