The W8JK antenna design
Invented by Dr. John D. Kraus, W8JK, in 1937, it uses two dipoles, both driven and out of phase with each other, to create a directional antenna no front to back ratio, though that works on six bands 20-17-15-12-10-6 meters and as a top loaded vertical on 40 meters

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
Antenna dipolo
Il dipolo aperto e' l'antenna piu' semplice, la piu' economica, la piu' facile da costruire
Antenne per il radioascolto
Non sono considerate antenne, nel sensostretto del termine, i pezzi di filo
