Trap Dipole
These devices are called Traps, but they are actually more like frequency sensitive switches. Each trap will require 80.5 inches (6.7 feet) of coax. soldered coaxial braid at the end of the coil where you started the winding.

The Short Dipole
in a step-down configuration to match the approximate, 12 ohm impedance of the antenna to a 50 ohm coaxial feedline. Traps allow operating one dipole on more than one frequency. As an example consider an 80/40 meter trap dipole.

After which, pull out the coaxial cable of the antenna. The coaxial table should then be unplugged from its exterior coaxial cable. Plug the car radio tv signal antenna booster together with he antenna’s coaxial cable.

Trap dipole
Despite the lack of literature, are there some trap projects that are easy to build, but perform better than coaxial traps? I must admit that I'm not to good at scratch building things as I'm better at fixing stuff or following a
