kb9ezl, I have an original Sigma 4, made by Antenna Specialists. I've reported that the S4 is a great antenna, but my signal reports never did show it to be much if any better that several other designs from a Starduster to the I-10K...among others that I own.

 

In reading the account of your results I find it curious that your S4 seems to be just as effective as what Bob85 reported for years with his Vector 4000 Hybrid...being easily detectable as superior to all others.

 

At some point on two occasions separated by a year or two back around 2006, I did some testing with my S4, while talking with Bob almost daily via email and comparing results to several other popular CB vertical antennas I owned. I did all kinds of things to my S4, and often as I was trying to get better results at Bob recommendations. I was never successful at seeing much if any improvement, and that disappointed both of us.

 

At some point near the end of these projects Bob told me that the S4 was not capable of getting the long range results his modified Vector showed him. I think now that Bob said that as a conclusion, but at first it really pissed me off that after all our words and lots of work over several years, back and forth up and down, he would tell me at the very end, after all was said and done, such was the case...not only with my S4, but also with one that he previously owned.

 

All of these accounts noted here present a rather obvious question as to what was reported over all time for this particular antenna. IMO, there is no way to really test, for sure, in the manner we CB hobbyists have at hand...to do real testing and thus we see differing reports at different locations. Your report is just another of such differing reports.

 

I thank you however for posting your results, and I don't question what you report, I also find my S4 to be a fine antenna.
