Jim, using 4ft of low loss Davis RF Bury Flex between LPA and KPA , 6m
is the one band with the biggest difference , KPA1500 reading 125 to 150
watts less . I've decided with the LP-100A in better line of site , I'm
going with it .

spread with the LP-100A reading 1500w the KPA-1500 is showing 1375w .
I also have an LP100A inline between my amp and my antenna switching.
What coax is between the amp and the LP100A, and how long is it? The
loss in this cable increases with frequency. Also, I believe that the
KPA1500 reads power on the amplifier side of the tuner, and it's not
lossless. I nearly always see a fractional dB between them.
