144 MHz halo antenna
Un dipolo fullsize ripiegato, omnidirezionale polarizzazione orizzontale, diametro 32 Cm, larghezza di Banda
A 144 MHz halo
This halo antenna was built to have an omnidirectional coverage while working in VHF contests
A 144 MHz halo
Si tratta di un dipolo a λ/2 richiuso a forma di cerchio,con gli estremi distanziati fra loro,e alimentato tramite Gamma Match
144 MHz Halo Antenna
2 meter Halo antennas I built, a horizontally polarized antenna for a 144 MHz WSPR propagation study and planned to stack these to increase omnidirectional gain
