So I was looking into a CB radio but why do we want it to die? sorry if im clueless
It's really at the bottom when comparing the available communication options.
CB is AM and is more susceptible to RFI (radio frequency interference).
The optimal antenna is very long, the shorter antennas are a compromise.
A CB antenna requires a lot of ground plane and requires tuning.
It's quite common to see a short CB antenna mounted in a poor location which results in less than stellar performance.
GMRS and ham on the other hand are FM which doesn't respond as much to RFI.
It is FM so the audio is good as well.
The antennas are much shorter. A 1/4 wave GMRS antenna is about 6" where a 1/4 wave CB antenna is about 102".
You can get longer GMRS and ham antennas to help performance vs getting shorter CB antennas which hurts performance.
The ground plane required by the shorter antennas really allows the antennas to be mounted in places a CB antenna can't.
You can get 1/2 wave GMRS and ham antennas that do not require a ground plane at all. You can get NGP (no ground plane) CB antennas too, but they use the coax as the ground plane and do not work as well as a ground plane dependent antenna.
Though it's always good to check tuning of a GMRS or ham (VHF/UHF) antenna, my experience is that they rarely if ever need tuning.
GMRS and ham allow for more power, 50 watts vs 4 watts.
GMRS radios can also talk to the FRS handheld radios.
You can get GMRS and ham radios for not much more than a CB radio.
Really about the only thing that CB has going for it is that it is still popular in many places and it doesn't require a license. GMRS and ham radio beat CB in every other way hands down.
