as Paul810 commented the GMRS/FRS are more prevalent...I live near the Gulf of Mexico so there are still a few old timers that monitor CB....(in a former life I was a USAFSS radio traffic analyst, so have more familiarity with the monitoring side)

I would like to tag this question on... I tried to on the cell phone antenna thread, but did not get any response..

there is a walking stick called the CI Gulo Gulo (sold by Wilderness Geek) that is billed as a cell phone gain antenna... I could not find any dB gain information about it... does anyone have any familiarity with this product?
