Shortened dipole for 10 & 40m bands - A shorten Dual-Band Dipole with overall length of about 11 m. For this antenna traps are substituted by inductors, in order to cover the 10 & 40 m. Bands.

Trapped dipole for 40 80m - I0SJC trapped dipole for 40 and 80 meters, traps done with 170 turns 1 mm diam, on a 3.2 mm cilinder in Italian.

8el 50Mhz / 70Mhz Dualband Yagi - Only just over 6 foot long, a compact 8 element dualband Yagi for 6 and 4 meters band. No traps or coils, no matching required. Simple to build by G0KSC

Dual Band Yagi 28Mhz and 50Mhz Priority listing - NO Traps or coils, NO matching required. Direct 50 Ohm feed. Easy to build and nothing else like it! Enjoy 50/28 with one feedline to a dual band high gain Yagi by G0KSC
