Hello Jean-François,
I think you will be very pleased with the MP-1. I used mine with a K2
from inside a 6th floor hotel room in Tourcoing, France during the WPX
contest last May and made several contacts of 1500-3000 km on 20m
at 5W through the heavy EU QRM.
Even a 1/8-wavelength counterpoise as you described is adequate to get
the input impedance to a point where the antenna tuner can easily match
the antenna. I use the 4SQRP Tenna-Dipper to easily tune it to my
operating frequency.
I found it helpful to have a 3/8-24 tap, as the threads tend to gall
fairly easily if you assemble/disassemble it often.
