Old mans whisdom :
Do NOT reward bad behavior.(Dutch :Ongewensd gedrag NIET belonen).
Unencumbered by any knowlege, everything is simple (Dutch : Niet gehinderd door ennige kennis, is alles eenvoudig).
So let's make life a bit less simple (less boaring) by reading more than 50 of my articles, and viewing 10 of my video presentations.

I AM RELOCATED :
Due to my declining physical health, at 23 june 2025 i moved to an alderly people care facility in Vleuten (Utrecht-NL).
Antenna : in feb 2026 we (me and my cousin Brian) installed an "End-fed 80m to 10m longwire" antenna.
Mean hight abt. 4 mtres. Hanging from the building to trees.
As a ounterpoise ("grounding") i used the concrete steel reinforcement, and the ALU frames of balconies of higher floor levels..
Results on 40m and higher are good, with wideband low VSWR.
But VSWR on 80m is bad, due to that used very good "ground".
Cause : The impedance at 3.65MHz is low at the feedpoint of the 1/4 lambda wire.
But still 49 times lower at the transformer connection to the TRX.
Unuseable
