This 4 foot CB antenna kit combines an AUC10 tall hood channel mount with a 4 foot top loaded antenna and 18 feet of coax for a quick setup ready to install on many full sized pickups and cars. 

The mount will require drilling in inconspicuous places under the hood on most vehicles It is 3 inches high from the base to the top of the mount, not including the stud.  It is about 1.25 inches from the base to the top of the highest mounting hole.  It will clear a hood channel groove up to 2 inches safely.  Deeper than that might be a tight fit.
