Topband: Inverted L Again

Ok all you antenna Gurus.

I have an inverted L question.

My inverted L is ~85 feet vertical and ~50 feet horizontal. 6ea 130 foot
radials laying on the ground. I would like to install a matching
network, possibly remote control (that is the easy part) that will
handle 1500 watts.

The MFJ 269 shows the following:

At 1830 kHz:
Rs=89
Xs= 23

Z=92
Phase=14 degrees

Rp=90
Xp=1350
SWR=1.9:1


At 2000 kHz:
Rs= 128
Xs=71

Z=146
Phase=28 degrees

Rp=166
Xp=303
Swr=2.8:1


The MFJ manual is a little cryptic as to what I'm actually seeing here.
I know you guys will set me straight!
Thanks and 73
Jim W7RY
