UHF Radio

These days it's most common to find CB radios sold in the UHF form.  The main reason for this is the wide bandwidth available and the fidelity (quality) of the Transmit (TX) and Receive (RX).
Many outdoors enthusiats make use of mobile Two-Way Radio devices, either built in to the vehicle (usually 5W Power Output TX) or handheld (in the range of 0.5W to 5W Power Output TX).  Whether mounted, static, vehicle or handheld, the more power the better the performance - i.e. clearer transmissions and longer working range.  Wherever possible, you should look at buying/using the highest power available (even if that means going on eBay to buy what you want from overseas).  There are a great deal of website out that that can advise on brands etc.
 
Below is a table with some useful information about TX/RX, Simplex and Repeater/Duplex channels in common use.  Repeaters may change and are highly dependent on Geography, especially in this Great State of ours.  Non-repeater channels without other allocation can be used for Simplex "chat" (i.e. regular usage):
