Shorten dipole antenna for 80m SSB band

Project of shorten dipole for 80m band idea has raised up during the trip and limited area condition.
I had just one fishing rod & no other place to hang up full size dipole. What is more the plot was quite narrow, unfortunately.

Antenna consists of two coils, 1:1 current balun (un-bal) and of course wires.
If you decide to wind the coil with the PCV pipe, please use the white one instead of grey, if possible.
All necessary details are described with the draft below . It’s a very important to hang this antenna as inverted-V to reach the near 50 Ohms impendance in the point of input signal.
