CB Radio antenna

I wonder if folks who do not live/travel in the western states understand that 2 meter will carry out to get you emergency help, where a CB will be blocked by all the mountains, and valleys we have. In the middle of the country, the terrain is much flatter, and the same goes for the far east, where a 4000 ft hill is what they call a mountain, and we look at 5-7,000, or even 10,000ft and more at times. I have, and use both while on my many Jeep excursions, and the calling between Jeeps is easier and more common with CB. That is when the CB's are about 2-3 miles at most. But, when we had an emergency rollover, and needed to get to the Kern County Sheriffs, we used the 2 meter, and were able to have clear communication to Randsburg, and Mojave, to airlift to Ridgecrest.
