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
Portable Dipole 40 30 17 m band
Wire dipole antenna that works on 40 30 and 17 meters band
Coax Trap dipole for 12m-17m-30m-40m-80m
diy antenna using 2.5mmq electric cable, a 1:1 balun
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.
