As Don indicated, one can use indirect measurements to measure
the R and X components of an antenna,

If you have a KAT100, you already have all what is needed to make
a good antenna analyzer.
Just push TUNE and let the KAT100 find a match, then
read out the L and C values from the KAT.

I have not worked out how to read out the L and C from the KAT100,
but it should be easy to make a simple program which reads them and
the frequency and displays the actual R and X, with sign.

I have used the KAT100 to measure the SWR of an antenna, just connect
a 50 Ohm dummy load and push TUNE, then connect the antenna,
and set the output level to 1 og 2 Watts, and key the K2 in CW mode,
the SWR leads will show the antenna SWR (the range from 1:1 to 1:5),

just my $0.02
