Don't trust the accuracy - into a real aerial it's very dependent
on the directivity of the coupler used. The VHF/UHF one is all but
useless (25dB typ.) and they spout a load of nonsense in section
3.2 'VSWR accuracy'.
If the VSWR reading changes with cable length, the sensor is not
I couldn't spot any directivity numbers for the hf ranges.
For all practical purposes it makes no difference that matters,
but to me it's somewhere between sleight of hand and snake oil.
