I use a comet sr wide band dual band antenna. Not sure of the part number, but it is their search and rescue mobile antenna. Im usung a comet nmo mount on the tail gate. It is a fold over design, very high gain and very wide banded. I will find a link for it, but having run many dual band antenna, this one seems to be the best dual bander i have used. I want to say they are around 60.00 or so. It has been smacked by many low branches and holding up well.
