80M loop ?

Propagation  is about as low as it goes   zero almost

max DX WSPR 80 is   890km!  OK2SAM

max DX in EU is 1300km pfff

In this situation  any antenna looks  trash ..

I changed back to the vertical shunt type antenna f.t.t.b.
I lowered the Delta loop..   or is it an inverted delta.
A 80m  wire loop automatic gets the delta / triangle form using 1 high central mast and trees around.

It is very easy to swap and get the vertical up again.
Almost as changing the scenery in a play.
Just lower the loop and up the wire  in a few minutes the loop is a vertical again.
This time I hung the vertical wire closer to he mast.  At the top about 40 cm  separated only.
This way this line is coupled with the steel mast  like a skeleton or  lecher line.
It tunes  SW about 1:1.6 at minimum   for a wire bit shorter then 20m.

But with this absolute  trash propagation  no conclusion  yet about its performance.
I compare my result with other EU WSPR stations like DK4XI always with superb good results on 80
