There are a few holes with the antenna review by nokones. (1) when his wife stated that the K30 sounded better, the husband stated that the performance was exactly the same. (2) Lack of other stations. I am in California and if I can find s single channel of the 40 available without other users stepping on all of the signals, I'd go right away and play the lottery. Listening to the audio provided by nokones, I didn't hear any other stations stepping on the test. While not legal, linier amplifiers, reak havok on CB. power mikes turned up to max (throw in effects such as echo and beeps) all add to the rule of "louder is better and further" which is typical for AM CB. (3) db gain of the two antennas? (4) Coax cable specs.
While i like the fact that nokones took the time to do a test, it was, in my opinion inaccurate for the couple of reasons i listed above. CB radio by it's technology and FCC limitations is and always will be a line-of-sight radio, much like FRS, non-repeated GMRS, non-repeated MURS etc.
More CB users need to step up and get their HAM Tech license. The test isn't that tough and opens a wide world of long distance communications (repeaters, clubs and events) without the bucket mouth users on CB (as CB was back in the 50's and 60's)
