Jean,
If you have measured the antenna with your antenna analyzer, it should
be OK.
First check diodes D1 and D2 in the KAT100.
If those are good, then turn to page 28 in the KAT100 manual and do the
SWR Bridge Null adjustment and the Power Calibration (page 29)
If you still have problems, turn to page 35 in the manual and do the
procedures as described in "Testing Relays, Inductors, and Capacitors".

Hi K2 members and Don W3FPR.
Last night I do have next failure.
I was transmitting with 50 W in CW with my K2/100 with in conjunction
with my KAT100 into a perfect aligned 7 Mhz dipole (SWR1/1)
Before starting I always do a tune with my K2 we never no the SWR is
bad hi.
The SWR indication on the KAT100 was outstanding 1/1,what I suspect
because I now the SWR of my antenne already was 1/1 !
After transmitting a while (5 minutes or so) the KAT100 SWR indication
was in the red zone,I stop transmitting immediately.
My RX level was dropping down to a zero level,propably a interruption
in the ANT1 connection of my KAT100.
I do change by means of the K2 command on the frontpanel to ANT2
connection and back to ANT1 connection.
Nothing happens to help the failure yet,same failure no RX on ANT1
connection ?
I do disconnect the KAT 100 unit and remove the power supply of the K2
and his KAT 100.
After all (toggling with the relays ???) I can receive again on both
ANT1 and 2 but I do have the correct impression that the receive level
on the ANT1 connection has been attenuated since I do hat this failure
last night !!!!!
