160-80-40m TRAP Dipol Antenna
Our antenna consists of three parts. The 9.82m section operates on the 40m Band and is terminated with 40m TRAP Trap. 3.35m section works in 80m band and ends with 80m TRAP

High-Q Coil Construction Techniques
High-Q coil inductors have something in common: the length of the coil can only be slightly longer than its diameter. In other words, high-Q coils have cube-like dimensions
Homebrew Your Own Inductors
Air-dielectric inductors can be made quite easily at home
Helical Coil
The inductance and self capacitance of a helical coil can be determined by entering its dimensions in the boxes above. The length of wire used is also calculated
