I've been through many brands of radios. But none of them compare to the Stryker line of radios...If you're looking for top shelf performance, they are the only clear choice.
Odd as I have talked mobile simplex for a lot further distance.I didn't say they're not, but 2m HAM radios, without a repeater, are only good for a couple miles.

Yes.
I wonder if he was thinking about handhelds maybe.
Yes that is correct. I should have clarified that.
But to compare apples for apples, I do believe a 4W hand held CB, with a full length antenna, will perform better than a 2m hand held.
I remember back in the late 80's, I'd frequently talk to my father in the evening, as we both stood out in our driveways, about five miles apart, using hand held CBs.
Have no idea where you all come up with the CB reaching farther than a 2 meter (excluding skip and power)? With my el-cheapo Baefeng hand held, ~4 watts or so, I can hit the repeater in Lake Wales, Florida (~20 miles) with a rubber duck antenna! I also have a CB hand held with legal 4 watts and RARELY hit Davenport, Florida which is about 4 air miles from me.
Watt for watt, 11m will generally go further than 2m for a couple of reasons.
First, 11m antennas are physically larger. A 1/4-wave CB antenna is ~108" vs ~20" for 2m. A physically larger antenna will pick up proportionately more signal than a smaller antenna, as long as both are resonant.
Second, 11m will pass through foliage and nonmetallic structures with less loss than 2m. 11m will also refract around terrain features with less loss than 2m.
The difference is similar to the difference between 2m and 70cm--70cm is even worse at penetrating foliage and refracting around obstacles than 2m. The only time 11m is at a disadvantage to 2m is when atmospheric noise levels are higher in the 11m band than the 2m band.
Prcguy, why is the 2m so much better than the 11m band?
Is it that the characteristics of higher frequencies just inherently allow it to reach farther out?
Or is it because the 2m radio has more power than the 4 Watt legal CB?
Or a combination of the two or something else?
Huh?
70cm refracts very well in urban enviorments. Especially when used with a quarter wave or even a half wave antenna.
There is actually a 14.6dB free space path loss advantage to CB over 2m where using identical power and 0dB gain antennas, CB would work better in space, but we are not in space and other factors are at play. Also, the size difference between 0dB gain antennas for CB and 2m is drastic.
A half wavelength on CB is about 18ft and a half wavelength on 2m is just a little over 3ft. When you shorten a CB antenna up considerably to say 3ft, its lost maybe 10 to 20dB efficiency compared to an 18ft antenna. A 3ft 2m antenna works quite well and an 18ft tall 2m antenna can approach 6dB gain over a 3.2ft long 2m dipole.
No, it can pass through smaller holes than 2m or 11m, but it is absorbed to a greater degree passing through solid walls and foliage. And if there is a low hill in the way it pretty much gets blocked, where 11m and 2m will refract around the hill.
