30 meter antenna Links →
Rotary dipole for 30/40 mt
Per la banda dei 30 metri,ho pensato che una verticale poteva andare bene
Small HF Antennas for 30m / 10.1 MHz and 20m / 14 MHz
I want antennas for both 10.1 and 14 MHz, but do not have room for a full-sized dipole
Tunable NVIS antenna for the 1.8 to 10 MHz
a horizontal half-wave dipole becomes a nvis antenna when it is installed at less than 1/4 wavelength above ground
Verticale per 30/40 MT
Il carico lineare per i 30 mt, ci poniamo il problema di come sorreggere il tratto centrale dell'antenna dove si dovranno alloggiare

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
