This Short Spiral Antenna is a great replacement for those long stock OEM whips that do not work with covers, get in the way of low overhead garage doors and are just a nuisance. This 7 1/2'' tall antenna is easily installed as a direct replacement for Can-Am RT, Victory, Yamaha Star Venture/Eluder, Indian and Harley AM/FM antennas.Included in kit is a new grommet for the Can-Am RT that will allow antenna to stay put and complete the installation along with a removable M6-1.0 threaded screw to mount on other models. Universal fit of M6-1.0 threaded antennas.
