Installation plan for 3.5 MHz Twep antenna (2025/04/22) 
I was thinking of a half-sloper, but not enough site area.
I regret the land I sold last year.
I think I can stretch it by bending the end of the element about 7m, but I don't have that 8m.
That's where JK1 SNS comes in.3.5 MHz twep antenna sent to us last year.We have begun preparations to install
However, the waterproof case for this coil is not sold.
So I asked my family to make a box out of veneer board.
At the top of the tower we decided to bend it into an inverted V shape
But in this way, it cannot be attached directly to the tower.
I was told by ChatGPT that I need an insulated brace, but I can't direct such a fabricated installation.
Tower Height 22m
Horizontal distance above the ground on the longer side 20m
Overall element length (3.5 MHz 1/2) 40m
   
Longer element length 29.73m
Shorter element length 10.27m
Length of rope needed as the shorter one does not reach the ground 12m
The idea was to stretch the ropes at an angle so that the top of the tower would also be distanced from the top of the tower by the ropes.
I can get the distance without having to machine the braces.
