1 s-unit been equal to 6db is not even close to correct on any cb or ham i ever owned eddie,
if that were true we would never see much difference in antennas,
the laziest meter of any of my radios is my jrc that is very close to 3db per s-unit,
i upset folk when they test amplifiers and i don't report signal 3 jumping to s9+10db,
if you want flowers ask somebody using a yaesu ft847 for a signal check,
this vid is much closer to what you can expect from a uniden cb

we will have to agree to disagree on signal reports, when i tested my imax against the i-10k one friend saw 1.5 s-units on a legal uk uniden 200 while another friend saw a much larger drop on a midland allan cobra 148 export clone and the reverse when i swapped back to the 10k, same pole/coax/radio at my end.
clearly there is not that much difference in gain but there that much difference in signal where my antennas are used,
im not testing in my dads field like i did back in the day.
