[1000mp] Q: Antenna Tuner, FT-1000MP Mark V Field

[Thomas Otterbein]

FT-1000MP Mark V Field

I use a Windom antenna for 40 -10 m.
Acc. to specification it is not usable for 15m.

When I try to tune the antenna with the installed
antenna tuner, the result is HiSWR and the transmitter
is shut down.
pwr adjustment is max. 100 watt.
With this adjustment it=B4s not possible to bring the antenna at
15m to a acceptable swr.

But when I adjust the pwr adjustment at the front panel=20
to about 20 watts, the tuner works and bring the antenna to=20
a good swr, 1,2 : 1.

When I now adjust the pwr adjustment at the front panel=20
to max. output 100 watt, the swr keeps the same value as
with 20 watts.

Question:
Why can the tuner not tune the antenne at max. pwr adjustment=20
at the front panel ?

Is the procedure to tune the antenna with the low pwr adjustment
and after tuning to got to 100 watts ok ?

At all other bands, were the antenna is in specified range, the
tuner works very well at the max. pwr adjustment.


Thanks for helping!
