Cobra 75 is a HHCH if I'm not mistaken. I like HHCH (Stryker makes my favorite so far but it is aimed at 10m) options…I try to keep at least one radio with a HHCH in my vehicles.

CB is cheaper for some, for others it's more expensive. A lot of people have the throw more power at it mentality when the CB's they are using either have horrible receivers or receivers that have never been aligned (Cobra's 25LTD receiver needs to be aligned from the factory for example). A good antenna is also key…I stay away from fiberglass antennas and don't really see much of a point in running 1/4 wave whips on CB (too large and too impractical to get as perfect of a radiation pattern as possible). Lowest point I'll mount an antenna is the top of the fender…otherwise it's up on the roof.
