My '72 has an old CB in it and the PO ripped the ant. off the side. I have a couple of GMRS radios that have 7-10 mile range. What is the benefit to putting a new CB in the rig? I am wondering if most people here use them to communicate with trail buddies or complete strangers. I'm just trying to figure out if it's worth the extra $$$ to put one in or whether or not the GMRS would suffice for most people's uses. What is the effective range of a decent CB unit anyway? I'm not bashing CB's by any means, just trying to get some information to base my decision on. Thanks for any info.
