Is the antenna on my bus a good fit for that radio? And will all I need is just adapter?
Different size coax cable will probably have a different "Impedance" measurement so I would be at the very least, know that all coax cable is not the same.
The cable connection itself, CB's require a PL259 connector.
2 standard coax cables are , RG-58 (standard coax) and RG-8x (premium coax).
And if your running dual antennae then you need to use an RG-59 dual antennae coax.
I wouldn't use the antenna already on the bus, it might just work but it will not work optimally. The antenna WILL need to be matched and tuned!
Do it right, go to a cb shop, most major truck stops can point you in the right direction for a CB-guru in the area or just use the web.
Here is one decent site with good basic info.
