Rich, Are you operating with the KAT500 in AUTO mode? You should train the antenna (using TUNE) on all bands and all antennas at 25kHz intervals for each band. Then change the KAT500 to MAN. The KAT500 will follow your frequency and change to the pre-set L/C values for that band and antenna

There are SWR parameters that can be changed in the KAT500 Utility.  I suggest you install this on your computer, connect the KAT500 and initiate the application. I have trained my KAT500 to use certain antennas on certain bands and for the lower frequencies, I have forced a tune ever 25 kHz.
