CB RADIO SWR METER - POWER METER - WATT METER

What is SWR? SWR stands for Standing Wave Ratio. Technically it's Voltage Standing Wave Ratio. Also called reflected power. To put it simply, radio waves like to jump off a certain length of metal according to the frequency. If the length of the antenna is proper for the frequency the RF will jump off the antenna efficiently. If the antenna is too long or too short for example, the RF(radio frequency) can not efficiently radiate from the antenna. What doesn't jump off is reflected back into the transmitter. This is the reflected power. The amount of reflected power is measured with a "SWR Meter". SWR is a measurement of the reflected power. A perfect ratio is 1:1. An ok ratio is 1:5 to 1. Borderline is 2:1. The lower the SWR the better the performance. Use an SWR METER to check and tune your antenna's standing wave ratio.
