A 20- & 30- or 20- & 39-Meter Trap Antenna
Thatit would be fun and doable to design a 20 & 30 or 20 &39meter vertical antenna, featuringa coaxial trap to isolate the20-meter portion
Antenna verticale per 30/40 metri
L'antenna ha una risonanza a circa 10500 MHz, quindi un po' piu in alto rispetto alla nostra fettina dei 30 metri
Antenna Bobtail-Curtain 30 Meters
It is made up of three vertical elements of 1/4 wave aligned in the same plane; each vertical element is spaced a length equal to ½ wave from the following vertical element
VDA Antenna for 30m
Project documents the construction and enhancement of a 30m vertical dipole array vda antenna
