CB Radio Questions
Hey guys,
so I'm kinda new to the whole CB scene, and I think it'd be sick to have one, and to also have a PA function with it. And as I said I'm new to CB's, and I've read reviews about some people not having a good enough antenna to support the SWR's (what in the world are those?) and it ended up frying the radio...so I was wondering if there's anyone out there, which I'm sure there is, with some CB knowledge and experience that can help me out here. I've been doin some research and the links below are the radio and the antenna I'm considering getting, so i was also wondering if those would be a good combo together? I would REALLY appreciate some feedback, thanks guys!

SWR stands for Standing Wave Ratio. It really doesn't have anything to do with power. SWR is a way of measuring impedance match between your antenna and you coax. You have 50 ohm coax, and most antennas are 52 ohms. You are trying to get your reading close to 1.1:1 SWR or 52 Ohms basically. This is accomplished by correct antenna length, and correct coax length. If the antenna also has poor ground, your SWR will be High. If the SWR is high, basically what happens is the output power returns to the radio as heat. So if you have say 4 watts going out, with a very high SWR, 2-3 watts may be coming back to the radio instead of being transmitted. NOT GOOD. You can also measure antenna match in reflected power, but SWR is easier. Many CB's nowadays have a built in SWR meter.
