The SBB-15 is a 1/4 wave on the 6M band. A 1/4 wave is only half an antenna, the other half is the ground plane underneath it. Installing a 1/4 wave on 10 different vehicles will create 10 different SWR results.
The SWR on a single band antenna can be adjusted by adjusting the length of the antenna to compensate for the difference in impedance provided at each mounting location. Not so with dual-band or tri-band antennas, the power feeding coil is pre-set at the factory.
If the SWR is elevated, adjust the antenna location until you find the best SWR.
