Build a 12/17 Meter Trap Dipole
Why a 12/17 meter rotatable dipole? Well, many folks have verticals for the lower bands, and multiband dipoles or beams for 20, 15, and 10 meters. But often you don't have an antenna for the 17and 12 meter bands

Trap Dipole for 17, 12 and 6 Metre Amateur Bands
His garden is only 50ft 15,24m long x 28ft 8,53m wide. This Aerial is still used for the 160, 80, 40 bands. In January 2015, John constructed another Trap resonated on 5,373MHz and inserted it between the 3,7MHz and 7,15MHz Traps to allow operation on the 60 Metre Band

Wire trap for 12m WARC band
Le trappole per cavi sono economiche, facili da assemblare in modo riproducibile, ma possono essere fragili meccanicamente facilmente deformabili per operazioni permanenti, su dipoli, V invertiti ecc.

The K9AY loop antenna for 160 and 80m bands

The K9AY loop antenna for 160 and 80m bands You don't have the space to put up a 4 beverage antenna's, an ewe or a 4-square and want 'good ears' on 160 and 80m? no problems try a k9ay loop antenna
