Hi Armin,
I am not ready either anymore on 160M and even 80M after recent
autumn storms...
As for your question, I wonder whether a very light horizontal
(loading ) wire of 30M which could start as early as from your Pine
height.
May be you would wrap an helicoïdal for the first 10M ( pine)
Most Inv L I read abt here have 10M vertical section and 30M
horizontal only; it would need further ( longer) radials though I
think.
Now look at this!

I am sure you have electric fences like these in ZL to keep your
nice sheeps together ! Don' t you? :-))
I plan to use one of these 10MM wide with 4 or 6 conductors. The
application are numerous: folded dipole, loaded areal and ( elevated)
radials, wrapped helicoïdal vertical, loaded radials, parallel
( symetrical ) feeders, etc ... I should find out what both losses
(and perhaps if needed velocity factors) are though!
I would imagine to shortcircuit relevant two wire out of four at
one extremity and two other at the other end to yield a loop, or
broadband an areal by putting them in parallel...etc...
Besides: 200M for 8 € is a steal!
73.
