"How long is the coax between the LP100 sensor and the K3? This can have a significant impedance transformation impact as you go to higher frequencies, leading to a different indicated SWR at each end."
The impedance changes, but not the SWR. Looking at this on a Smith Chart, you can see that you just rotate around a constant SWR circle. Minus coax losses of course, which are negligable when we're talking a few feet at HF.
