The length L is calculated using standard dipole formulas 468/Frequency in Mhz, for feet, or 143/Frequency in Mhz for meters with a loss factor of about 2-5% factored in. Two shorting straps are soldered close to the ends at 0.07L, a distance of 0.86L

short ham antennas are not as efficient nor as effective as a full length half wave dipole regardless of the configuration chosen

you can make a 50 ohm version directly from RG-58 or RG-8 / RG-213 cable

Antenna con molta piu' silenziosita', quindi miglior rapporto segnale rumore, molta piu' larghezza di banda

A variation of the dipole is an antenna called a folded dipole. It radiates like a dipole but sort of looks like a squashed quad

Antenna a copertura continua da usarsi solo in ricezione, ottima per l'ascolto con QRM cittadino e con disturbi atmosferici

40-30-20 m Short Antenna small no bulky traps minimum of components

The Folded Dipole is not used much amongst Radio amateurs, probably due to the fact that this antenna uses twice as much wire as a single-wire dipol

a broadband antenna for receiving broadcast stations

The reason it's called an all band antenna is because if it's carefully constructed and installed, this antenna will work well on all bands from 80 to 10 meters

A folded dipole is a dipole antenna with the ends folded back around and connected to each other, forming a loop
