Hi Andy,

just a small c= orrection to the datas of previous message.. time lapses

Hello Andy,

sorry for the local QRM, the neighbors of Markus are more = fair.. hi
May be later they have a short sleep and conditio= ns improve :-)
I have never made measurements of current at= the antenna base, it is a
bit complicate because it is on= the roof of the house (or according
the
= definition of a friend on the Saratga deck), just recorded impedance
plots with my N2PK VNA. If I have to trust on my RF ammeter in t= he
shack (about 40m of coax away) it should be in the rang= e of 1A but I
guess it is peak not rms. The antenna is fed= via a transformer made
with 2 stacked FT 240-43 N1=3D20T = and N2=3D14T (2:1 transformer) and
neglecting the small tr= ansformation given by transmission line the
impedance at r= esonance including all losses is close to 25 ohm. Of
cours= e this nice reading is due to my single radial.. or the Saratoga
deck: the roof is made of sandwich panels (about 700 sqm at 35m fro= m
the ground) and I spent some time placing jumpers betwee= n quite all
the
panels ;-) so the measure= d impedance is very close to the simulated

Just for fun could send you by = mail some pictures ;-)

Hope to see later y= our reports

Hello Markus,

apparently this morning the= re is a Turin-Nuerberg duct!
