A 9 dBi very high gain antenna for the open-range.  Tuned and centered for GMRS. 

Fed by RG58-C/U coax, with an FME connector for easy routing through bullbar mount holes, and vehicle firewalls or headliners.

This antenna has a moderately strong base spring and designed to be mounted on a sturdy mount such as a metal front bumper/bull bar, or roof rack.  Mounting through body panels would not be recommended, as the moment generated by wind or off-highway vehicle movement may bend and potentially yield body panels.
