I am sure they make better antennas that Francis, but for me, mine has worked great. I can talk and receive pretty well, and they are very flexible, which helps prevent them from breaking.
I have heard alot of CB advertisements for the "monkey made" antenna, and if you need one that you can tune, most anybody I have talked to that has these will recommend them.
For me, I just have a stock Cobra 29 radio, nothing at all done to it, and a single Francis antenna. Gets the job done for me in a rather inexpensive manner, compared to what you can spendon radios and equipment if you are heavy into it. I might upgrade to to a nice set up at some point, but I will probalbly go toward a HAM license at that point.
