Trap construction
In search of a software for the hatches: Coaxial-traps. Why also coaxial hatches? I chose this system, because not having 1.5 mm² copper wires to use, I had however a lot of cable 75 ohm coaxial for CCTV

An Attic Coaxial-Cable Trap Dipole for 10, 15, 20, 30, 40, and 80 Meters
A coaxial-cable trap dipole antenna installed in the attic provides a surprisingly effective solution to HF
Simple Building and Tuning of Traps
Traps are useful for multiband operating of all kinds of antennas
40 & 80 meter trap dipole
Coil 78 turn of insulated copper Wire no spaced
Coaxial Traps Grid-dip meter method
A trap is a parallel resonant circuit network that can perform either of two functions in an antenna system
Coil Design
The coil design is one of the most difficult and important parts of the coilgun
